Gaetano Pesce (8 November 1939 – 3 April 2024)

Moving against the stream of rational, functional modernism in the 1960s and early 70s, Mr. Pesce experimented with materials and production methods to create furniture pieces imbued with political or religious meaning for brands from Cassina to B&B Italia.

Many would go on to become icons of Italian design including the Up5 chair – an innovative vacuum-packed chair designed to resemble a female prisoner – which he designed for B&B Italia precursor C&B.

Pesce moved to New York in 1983 and began to move away from mass production to create "standardised series" in everyday materials like resin, adapting conventional production techniques to create varied and imperfect outcomes.

The result are pieces such as the 1884 Pratt chair, which toe the line between functional design and decorative art, helping to create a new category that would later become collectible design.

Mr. Pesce was born in the Italian city of La Spezia in November 1939, only two months after the start of world war two.

As was common at the time, he trained in both architecture and design, studying first at the University of Venice and later at the Venice Institute of Industrial Design.

Among his architecture projects is the Organic Building in Osaka from 1993, with its plant-covered facade made of orange fiberglass that served as a precursor to today's vegetation-covered green walls.

But Mr. Pesce's most pioneering and well-known work happened in the world of design. In the late 1960s, he became one of the leaders of Italy's Radical Design movement, rejecting modernism's rigid focus on forms dictated by function.

Instead, Pesce focused on the idea that functional objects, much like art, could carry a deeper message.

One of the most famous examples is the controversial Up5 chair from 1969, which manufacturer B&B Italia describes as "the first product of Italian design with a political meaning".

The Power Of Polymer: Unfolding The Magic Of Polyurethane Foam Production

INTRODUCTION:

In the dynamic and evolving world of polymer science, one name specifically stands out due to its versatility and vast applicability – Polyurethane. A byproduct of the mind-boggling chemical reaction between two liquid materials, polyurethane is a unique type of polymer that effectively transforms into a foam. This article endeavors to offer you a detailed look into the exciting world of polyurethane foam production

THE DYNAMIC DUO:

Polyurethane foam is produced when two chemically distinct liquid materials – commonly referred to as the “”A”” component and “”B”” component – are combined under specifically controlled conditions.

The “”A”” component, or Polymeric MDI (methylene diphenyl diisocyanate), is a reactive isocyanate that boasts a relatively low viscosity level, enabling it to mix flawlessly with the “”B”” component. It has a brownish coloration and often exudes a slightly sweet smell.

Meanwhile, the “”B”” component, also known as Polyol, is a polyether compound that is generally less reactive than its “”A”” counterpart. It is characterized by a pale, almost transparent color and presents a tasteless, odorless profile.

POLYURETHANE PRODUCTION:

Let’s delve into the fascinating process through which these two distinct liquids join forces to produce the mighty polyurethane foam.

When combined, the polyether polyol and the polymeric MDI kickstart an exothermic chemical reaction that generates a considerable amount of heat. During this process, tiny gas bubbles are formed, which get trapped within the polymer structure, eventually giving rise to what we commonly recognize as foam. This intriguing process is commonly referred to as “”foaming.””

The reaction’s speed and the cell structure’s quality are heavily dependent on the specific quantities and properties of the A and B components. Manipulating these parameters allows for the production of a wide variety of foam types from rigid and semi-rigid to flexible. Additionally, various catalysts and surfactants can be added to control the cell structure’s size and distribution, as well as the reaction speed.

The transformation process from a liquid state to a solid, foamed state is surprisingly quick – often taking less than a few minutes. However, it’s noteworthy to mention that the foam continues to cure and reach its complete strength over the course of a few hours or even days.

APPLICATIONS OF POLYURETHANE FOAM:

The versatility of polyurethane foam is extraordinary. From furniture and bedding to automotive applications, thermal insulation in construction, and even in the footwear industry, polyurethane foam has spread its roots far and wide.

UNDERSTANDING THE SCIENCE:

The combination of a polyether polyol and a polymeric MDI generates not just heat but also a new product – urethane. Urethane forms strong, resilient bonds that contribute to the flexible, durable nature of the resultant foam. This is what makes polyurethane an excellent choice for various applications that require durability, flexibility, and excellent thermal and acoustic insulation properties.

In conclusion, the creation of polyurethane foam from two liquid materials is a mesmerizing example of polymer formation, which encapsulates the dexterity and capability of synthetic chemistry. By manipulating the compounds’ properties and the conditions under which the reaction occurs, scientists and engineers have managed to expand the realms of possibility, thereby furthering the boundaries of modern industrial applications. Thus, polyurethane foam not only offers an excellent material for various purposes but also profoundly echoes the power and potential of polymer science.

Insulation 101: Benefits and Types of Insulation

Commercial building owners invest in quality insulation materials because of their numerous benefits. Insulation helps enhance the overall performance of any commercial building, decreases harmful greenhouse gas emissions, and helps keep your energy bills from increasing.  

In addition, adding insulation to your establishment can also reduce the number of noises coming in and out. This is beneficial mainly for establishments that require better acoustics or sound barriers. Let's learn more about the different types of insulation material available now.

Batt Insulation

Professionals use batt insulation efficiently, one of the most affordable options available today. It comes with two options; with or without facing. Professionals must place this per specifications to resist water vapor transfer. Most insulation today contains recycled materials such as sand. Fiberglass also includes sand which is an environmentally friendly content source.

Batt insulation can either be fiberglass, cotton, or stone wool blankets. Fiberglass is the most common type out of the rest. It is the perfect insulation for attics, walls, ceilings, crawl spaces, and basements.

Blown-in Insulation

When it comes to blown-in insulation, proper installation is a must. Professionals should utilize special equipment and safety measures to ensure long-term function. In addition to being primarily recycled, cellulose blown-in insulation also contains fire-retardant properties. It also resists insects, rodents, and mold and impressively creates a good sound barrier. Once the professionals finish the application, there are also available products with insulation that you can incorporate to enhance your commercial building, such as an insulated roof hatch.

Spray Foam Insulation

If you prefer an insulation material that forms an air barrier, then spray foam insulation should be the option on your list. This material can effectively cover your walls, floors, and ceiling cavities against air movement. This includes spaces around electrical outlets, light fixtures, and walls that meet windows and doors.

Professionals use spray foams in open cavities, like in new construction, crawl spaces, rim joists, and attics. You can also use this on remodeled homes. You can apply the spray foam if the cavities are unrestricted and accessible. Here are the two varieties of spray-foam insulation;

Closed-cell SPF- is a type of spray foam insulation that adds structural strength and is a rigid, vapor-resistant foam that doesn't require replacement in case of a flood.

Open-cell SPF- spray foam insulation that offers identical insulation advantages but does not act as a water barrier or vapor retarder.

Air Sealing

Controlling the air leakage of an establishment is critical to effective insulation. You can do a great job protecting an establishment, but if air can seep through gaps or cracks in the building envelope, you lose your valuable heated or conditioned air.

Concrete Block Insulation

A concrete block's center contains insulating materials such as polystyrene, polyisocyanurate or polyiso, and polyurethane. The hollow centers of concrete blocks can be filled by pouring and injecting loose foam beads or liquid foam. Some professionals create concrete blocks that support rigid foam inserts.  

Reflective System

Unlike most typical insulation, which resists convective and conductive heat flow, reflective insulation works by reflecting radiant heat away from your commercial building. These insulation types are best for hot and humid climates, primarily if you have cooling air ducts in the attic. According to research, radiant barriers can lower cooling costs by up to 5% to 10% when utilized in a warm, sunny temperature.  

There are still other insulation options available. Ensure to collaborate well with your architect, engineer, or contractor to choose the best insulation option based on your commercial building's needs and your project budget.

Why Garage Door Insulation Matters: A Complete Guide for Homeowners

When it comes to home improvements, many homeowners overlook the importance of garage door insulation. However, insulating your garage door offers significant benefits, from energy savings to enhanced comfort and even noise reduction. This guide will walk you through the benefits of garage door insulation and the various options available to help you make an informed decision for your home.

Benefits of Garage Door Insulation

Energy Efficiency

One of the most compelling reasons to insulate your garage door is the improvement in energy efficiency. Uninsulated garage doors allow heat to escape during winter and let cold air enter during summer, making your home’s heating and cooling systems work harder.

Temperature Regulation

Insulating your garage door helps maintain a consistent temperature in the garage itself. This is especially important if you use your garage as a workspace, home gym, or storage area for temperature-sensitive items. During winter, an insulated garage stays warmer, making it more comfortable to spend time in. In the summer, insulation helps keep the garage cooler, reducing the need for fans or air conditioning and protecting items stored in the garage from extreme temperatures.

Noise Reduction

Another significant benefit of insulation of garage doors is noise reduction. Insulated doors help muffle outside noise, such as traffic or neighbors, and minimize sound from within the garage, such as tools, vehicles, or loud machinery. This can be particularly beneficial if your garage is attached to your home, as it helps maintain peace in living spaces.

Increased Durability

Insulating your garage door can also extend its lifespan. Insulated doors are less likely to warp, crack, or become damaged by extreme temperature fluctuations. The added layer of insulation can help protect the door from the elements, reducing the need for frequent repairs and maintenance.

Improved Home Value and Curb Appeal

A well-insulated garage door not only adds value to your home but can also enhance curb appeal. Many insulated garage doors come in various styles and finishes, allowing you to choose one that complements your home’s exterior. The energy-efficient features of a well-insulated garage door can be a selling point if you plan to put your home on the market.

Options for Garage Door Insulation

Polystyrene Insulation

Polystyrene, often referred to as rigid foam, is one of the most common types of insulation used for garage doors. It comes in panels that are fitted between the door’s metal sections.

Polyurethane Insulation

Polyurethane insulation is more efficient than polystyrene. It’s a liquid foam that expands and hardens inside the door, creating a solid layer of insulation. This type of insulation provides a higher R-value (a measure of thermal resistance), meaning it offers better temperature control. 

Reflective or Radiant Barrier Insulation

Radiant barrier insulation reflects heat away from the garage, making it especially effective in warmer climates. This type of insulation is typically made from reflective materials, such as aluminum foil. 

DIY vs. Professional Installation

Garage door insulation can be a DIY project, particularly if you’re working with polystyrene or reflective insulation. However, professional installation may be necessary for more complex options, like polyurethane insulation, to ensure it is applied correctly and provides the maximum benefit.

Insulating your garage door by Den Garage Doors offers multiple benefits, including improved energy efficiency, noise reduction, and increased comfort. Contact them at +303 418 8085 to have an estimate.

Flexible PCB Manufacturer & Assembly – One-stop services

Hitech Circuits Co.,Ltd is a professional flexible pcb, FPC printed circuit board manufacturer,  supplier from China,  due to its features of bendable, reducing product size, good heat dissipation and solderability, easy assembly and low overall cost etc, it is widely used in mobile phones, wearable smart devices, automobiles,  medical treatment,  and industrial control etc. If you are looking for a reliable flexible PCB board partner in China, please don’t hesitate to contact sales@hitechcircuits.com 

SMT: Technical Points for Mounting Flexible PCB

There are many differences between the flexible PCB SMT process and the SMT solution of the traditional rigid PCB. If you want to do the SMT process of the flexible PCB, the most important thing is positioning, because the hardness of the flexible PCB is not enough, it is softer, and if the special carrier is not used, it cannot be fixed and transmitted, and the basic SMT processes such as printing, patch, and furnaces cannot be completed. The key points of pre-processing, fixing, printing, patch, reflux welding, testing, and division plates of flexible PCB in the production of SMT production are specified as below.

1. Flexible PCB pretreatment

The flexible PCB is softer, and it is generally not a vacuum packaging when it leaves the factory. It is easy to absorb the water in the atmosphere during the transportation and storage procedures. You need to prepare pre-baking treatment before the SMT patch process and slowly discharge the water, otherwise, under the impact of reflux welding at high temperatures, the water absorbed by the FPC quickly vaporizes into steam, which can easily lead to poor flexible PCB layer departure and foaming.

Generally, pre-baking temperatures are 80-100℃ for 4-8 hours, however, under the special condition, the temperature can be raised to more than 125℃, but need to shorten the baking time accordingly. Before baking, be sure to take a small sample test to determine whether the flexible PCB can withstand set baking temperatures, you can also consult flexible PCB manufacturers with appropriate baking process. When baking, don’t put too much flexible PCB for one time, 10-20 panels are more suitable. Some flexible PCB manufacturers may put a piece of paper among each flexible PCB to isolate them and at the same time need to check if the paper can bear the baking temperature, if it cannot be, then pull off the paper before baking. After baking, if the flexible PCB does not have the issues like visible change in color, out of shape, and up warp, etc and then need the IPQC to do sampling inspection.

2. Flexible PCB paste printing

The flexible PCB does not have a very special requirement for the ingredients of the weld paste. The size and metal content of the tin ball particles depends on whether there is a fine pitch IC on the flexible PCB, but the printing performance of the solder paste is higher in FPC, welded paste should be easy to print and eliminate modeling and can be firmly stacked to the flexible PCB surface, there will not be adversely obstructing the steel mesh leakage or collapse after printing.

Because the flexible PCB is loaded on the carrier plate, the flexible PCB has a high-temperature resistant tape for positioning to make its plane inconsistent, so the printing surface of flexible PCB cannot be as smooth as rigid PCB, and has same thickness and hardness, therefore, it is not suitable to use metal scraper, but should use the hardness of 80-90 degrees of polyurethane scraper. It is best to have an optical positioning system for tin paste printing machine, otherwise it will have a great impact on the quality of printing. Although the flexible PCB is fixed on the carrier, there will always be some small gaps between flexible PCB and the carrier, this is the biggest difference from the rigid board, so the setting of the machine parameters also has a greater impact on printing effects.

Printing station is also the key station to prevent flexible PCB dirt, workers need to wear finger stall during operation, at the same time to keep the station clean, and often wipe the steel mesh, to prevent solder paste pollution of the gold finger and gold buttons of flexible PCB.

3. Flexible PCB mounting

According to the characteristics of the product, the number of components, and the efficiency of the patch, needs to use the middle and high-speed patch machines to install. Since the optical mark label for positioning is available on each flexible PCB, SMD paste on the flexible PCB is not very different from the installation on the rigid PCB. It should be noted that although the flexible PCB is fixed on the carrier board, its surface cannot be as flat as rigid board, there will definitely be little gap between flexible PCB and the carrier, therefore, the descending height and blowing pressure of the suction nozzle should be set accurately, and the moving speed of the suction nozzle should be reduced. At the same time, the majority of flexible PCB are connected plates, and the finished product rate of flexible is relatively low, so it is normal for the whole panel to contain some defective board, which requires the bad marks recognition function of the SMT machine, otherwise, the production efficiency will be greatly reduced when the production of this kind of non-integrated panel is good.

4. Flexible PCB Reflow soldering

Mandatory hot air convection infrared reflow furnace should be used, so that the temperature on the flexible PCB can be more uniform change, reduce the occurrence of poor welding. If single-sided tape is used, it can only fix the four sides of the flexible PCB, and the middle part is deformed in the hot air condition, so that the welding plate is prone to tilt, and the molten tin (liquid tin at high temperature) will flow and produce air welding, continuous welding and tin beads, so that the process defect rate is high.

(1).Temperature curve test method:

Due to the different heat absorption properties of the carrier plate and the different types of components on the flexible PCB, their temperature rises at different rates after being heated in the reflow welding process, and the heat absorbed is also different, therefore, carefully setting the temperature curve of reflow furnace has a great influence on the welding quality. The relatively safe method is that according to the load interval during actual production, put two pieces carrier plates with flexible PCB on the front and back of the test board, at the same time, a component is installed on the flexible PCB of the test carrier plate, and the test temperature probe is welded to the test point with high temperature solder wire, meanwhile fix the probe wire on the carrier plate with high temperature resistant tape. Note that high-temperature tapes cannot cover the test point, the testing point should be selected at the welded joints and QFP pins near the side of the carrier plate, such test results can better reflect the real situation.

(2).Settings of temperature curve:

In the furnace temperature debugging, because the flexible PCB temperature uniformity is not good, so it is best to use the temperature curve of temperature rise/heat preservation/reflux, so that the parameters of each temperature area is easy to control, in addition, flexible PCB and components are less affected by heat shock, in this way, the parameters of each temperature area are easy to control. In addition, according to the experience, it is best to adjust the temperature of the furnace to the lower limit of the technical requirements of the welding paste, the wind speed of the welding furnace generally uses the minimum wind speed that the stove can be used, the back welding furnace chain should have good stability and cannot be shake.

5. The Test Division of Flexible PCB

Because the carrier plate absorbs heat in the furnace, especially the aluminum carrier plate, the temperature is higher when it comes out of the oven, so it is best to add a forced cooling fan at the furnace to help rapid cooling, at the same time, operators need to wear heat insulating gloves to avoid being burned by the high temperature carrier plate, when taking the finished flexible PCB from the carrier plate, the force should be uniform and cannot use much force to avoid the flexible PCB being torn or generate crease.

Doing visual inspection for the flexible PCB under the 5x magnifying glass, focusing on checking the surface residual gum, color change, golden finger dipping tin, tin bead, IC pin empty welding, and connected welding, because the flexible PCB surface cannot be flat, the misjudgment rate of AOI is high, so flexible PCB is generally not suitable for AOI checks, but through the use of special testing fixtures, flexible PCB can complete ICT and FCT testing.

Because flexible PCBs are mostly connected together, workers may need to do board split before the ICT and FCT testing, although tools such as blades and scissors can also be used to complete the division operations, the work efficiency and the quality of the operation are low and the scrap rate is high. If it is a large quantity of special-shaped flexible PCB, it is recommended to make a special stamping section mold and perform stamping segmentation, which can greatly improve the operating efficiency, meanwhile, the edge of the flexible PCB is neat and beautiful, it can effectively avoid welded tin cracks.

Conclusion

For SMD mounting on the flexible PCB, accurate positioning and fixing of the flexible PCB are the key points, and the key of fixing is to make the appropriate carrier plate; Secondly is the pr -baking, printing, patch and reflux welding of flexible PCB, obviously, the FPC's SMT process is more difficult than the rigid PCB, so it is necessary to accurately set the process parameters and strict production process management is also important. It is necessary to ensure that operators strictly implement every rule of SOP, engineers and IPQC should strengthen inspection,   and discover abnormal conditions of production line in time, analyze the causes and take necessary measures, so as to control the defect rate of production line.

The Power Of Polymer: Unfolding The Magic Of Polyurethane Foam Production

INTRODUCTION:

In the dynamic and evolving world of polymer science, one name specifically stands out due to its versatility and vast applicability – Polyurethane. A byproduct of the mind-boggling chemical reaction between two liquid materials, polyurethane is a unique type of polymer that effectively transforms into a foam. This article endeavors to offer you a detailed look into the exciting world of polyurethane foam production

THE DYNAMIC DUO:

Polyurethane foam is produced when two chemically distinct liquid materials – commonly referred to as the “”A”” component and “”B”” component – are combined under specifically controlled conditions.

The “”A”” component, or Polymeric MDI (methylene diphenyl diisocyanate), is a reactive isocyanate that boasts a relatively low viscosity level, enabling it to mix flawlessly with the “”B”” component. It has a brownish coloration and often exudes a slightly sweet smell.

Meanwhile, the “”B”” component, also known as Polyol, is a polyether compound that is generally less reactive than its “”A”” counterpart. It is characterized by a pale, almost transparent color and presents a tasteless, odorless profile.

POLYURETHANE PRODUCTION:

Let’s delve into the fascinating process through which these two distinct liquids join forces to produce the mighty polyurethane foam.

When combined, the polyether polyol and the polymeric MDI kickstart an exothermic chemical reaction that generates a considerable amount of heat. During this process, tiny gas bubbles are formed, which get trapped within the polymer structure, eventually giving rise to what we commonly recognize as foam. This intriguing process is commonly referred to as “”foaming.””

The reaction’s speed and the cell structure’s quality are heavily dependent on the specific quantities and properties of the A and B components. Manipulating these parameters allows for the production of a wide variety of foam types from rigid and semi-rigid to flexible. Additionally, various catalysts and surfactants can be added to control the cell structure’s size and distribution, as well as the reaction speed.

The transformation process from a liquid state to a solid, foamed state is surprisingly quick – often taking less than a few minutes. However, it’s noteworthy to mention that the foam continues to cure and reach its complete strength over the course of a few hours or even days.

APPLICATIONS OF POLYURETHANE FOAM:

The versatility of polyurethane foam is extraordinary. From furniture and bedding to automotive applications, thermal insulation in construction, and even in the footwear industry, polyurethane foam has spread its roots far and wide.

UNDERSTANDING THE SCIENCE:

The combination of a polyether polyol and a polymeric MDI generates not just heat but also a new product – urethane. Urethane forms strong, resilient bonds that contribute to the flexible, durable nature of the resultant foam. This is what makes polyurethane an excellent choice for various applications that require durability, flexibility, and excellent thermal and acoustic insulation properties.

In conclusion, the creation of polyurethane foam from two liquid materials is a mesmerizing example of polymer formation, which encapsulates the dexterity and capability of synthetic chemistry. By manipulating the compounds’ properties and the conditions under which the reaction occurs, scientists and engineers have managed to expand the realms of possibility, thereby furthering the boundaries of modern industrial applications. Thus, polyurethane foam not only offers an excellent material for various purposes but also profoundly echoes the power and potential of polymer science.
