LED PCB Assembly

What is the LED Circuit Board assembly?

Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights.

We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.

Number of layers for LED PCB

These layers are made up of aluminum and magnesium, but now have Copper base material  and Ceramic base materials for LED PCB industry, we can meet it.

Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too.

Types of layers for LED PCB Assembly

Normally, the base layer is made using aluminum alloy metal.

This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat.

A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics.

It is highly heat resistant and protects the PCB against heat and mechanical stress.

The circuit layer, which is covered by a copper foil which can range from one to ten ounces.

LED Board type- single or in panel

Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time.

Some LED PCB Assembly is done on a single board while others are done on panel boards.

LED PCB Assembly Process

Roughly, the PCBA process can be divided into theses phases: soldering paste printing > SMT (surface mounted technology) > reflow soldering > AOI (automated optical inspection)> THT (through-hole technology) > wave soldering > touch-up and cleaning > IC-programming > FCT (functional tests) > aging testing. 

Below we show you the process.

Step1. Summarizing Project Information

Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly:

Gerber

BOM

LED PCB specification

Quotation quantity

Once you have gathered these information, you can contact us and request for a quote.

Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be.

Step2. Discussion and details about custom LED PCB Assembly

Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities.

For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want.

Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them.

Step3. Sample and feedback

After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc.

For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected.

The Bill of Materials is then generated from the information installed on the LED PCB.

All this information is used to assemble components which are identified from MOB to the LED PCB.

After that, the routing of traces is determined to each component, based on the size, shape of the circuit board and location of connectors.

1. Surface-mount technology

SMT: SMT stands for “Surface Mount Technology“.  The SMT components are very small sizes and comes in various packages like 0201, 0402, 0603, 1608 packages for resistors and capacitors. Similarly for Integrated circuits ICs we have SOIC, TSSOP, QFP and BGA.

The SMT components assembly is very difficult for human hands and can be time taking process so it is mostly done by automated pick and place machine.

2. Through-hole manufacturing

THT: THT stands for “Through hole Technology”. The components with leads and wires, like resistors, capacitors, inductors, PDIP ICs, transformers, transistors, IGBTs, MOSFETS are example.

The component has to be inserted on one side of PCB and pulled by leg on other side and cut the leg and solder it. The THT components assembly is usually done by hand soldering and is relatively easy.

Printed Circuit Board Assembly Techniques

There are only two common PCBA techniques available for use by a PCB designer. The methods are:

1. Automated PCB Assembly Techniques

Generally, this technique employs the use of state of the art machines, which are fully automatic. For example, the surface mount components are worth positioning with the aid of an automated pick and place machine.

Again, reflow soldering is commonly for surface mount components usually done in a reflow oven. An automated solder stencil is also used to apply the solder paste on the PCB.

Finally, high tech inspection machines are used to confirm and check the quality of the PCBA. Some of which include: Automated optical inspection machine (AOI), X-ray inspection machines, etc.

Above all, due to the precise monitoring, control of soldering, no human input and versatile machines.

This technique ensures utmost efficiency, output consistencies, and limits defects.

2. Manual PCB Assembly Techniques

This method is favorite for use with through-hole parts, which needs manual placement on the board. Besides, with these through-hole parts, it’s advisable you use wave soldering. Note that in the through- hole assembly process, you need to place the components and electronics on the PCB.

After that, you use wave soldering to solder the leads. Typically, you will need an individual to insert a component into a marked PTH. Once done, transfer the PCB to the next station where the next person will be on standby tasked with fixing another part.

What are the Benefits of SMT PCB Assembly?

SMT assembly provides many benefits and some of them are as follows:

It can be used to incorporate small components.

In SMT, the components can be placed on both sides of the board.

It assures high component densities.

Fewer holes need to be drilled for surface mounting than through-hole.

It require low initial costs and time for setting up the mass production.

SMT is the simpler and faster-automated assembly when compared to through-hole.

Errors regarding the component placement can be easily rectified. 

Surface mount  PCBs feature strong joints, which can easily withstand vibrations. 

What are the techniques used in Surface Mount Technology?

There are several techniques for the reflow process. After applying the solder paste or a flux mixture on the board and after placing the components, the boards are conveyed to a reflow soldering oven. The techniques used for reflowing soldering include infrared lamps, hot gas convection, fluorocarbon liquids with a high boiling point, and so on.

What are the different testing methods used in SMT PCB Assembly?

Hitech Circuits as the PCB assembly manufacturer, we perform the following testing and inspection to ensure the quality of surface mount PCBs.

Automated Optical Inspection (AOI): This is performed before and after the soldering to identify the component placement, presence, and solder quality.

X-ray Testing: In this type of testing, the operator relies on the X-ray images of the PCB to check the solder joints and lead-less components such as Quad Flat Packs and ball grid arrays, which are generally not visible to naked eyes.

In-Circuit Testing (ICT): This method is used to detect manufacturing defects by testing the electrical properties in the SMT Assembly.

What type of files or documents should I send for SMT PCB Assembly? 

Gerber Files: The file contains all details of physical board layers including solder masks, copper layers, drill data, legends, and so on.  

Bill of Materials (BOM): This contains information on the list of items needed for the PCB manufacturing and the instructions of manufacturing. 

Pick and Place File: This file contains information on all components to be used in the PCB design and their rotation and X-Y coordinates.

The whole process of PCB Assembly

1. Bare board loader machine

The first step in the PCB assembly is to arrange the bare boards on the rack, and the machine will automatically send the boards one by one into the SMT assembly line.

2. Printing solder paste

When PCB on the SMT production line, firstly, we have to print solder paste on it, and the solder paste will be printed on the pads of the PCB. These solder pastes will be melt and solder the electronic parts to the circuit board when it passes through the high-temperature reflow oven.

In addition, when testing new products, some people will use film board/adhesive cardboard instead of solder paste, which can increase the efficiency for adjusting the SMT machines.

3. Solder paste inspection machine(SPI)

Since the quality of solder paste printing is related to the quality of welding of subsequent parts, some SMT factories will use optical machine to check the quality of solder paste after printed the solder paste in order to ensure stable quality. If there any poorly printed solder paste board, we will wash off the solder paste on it and reprint, or remove the excess solder paste if there is redundant solder paste on it.

4. High speed SMT machine

Usually, we will put some small electronic parts (such as small resistors, capacitors, and inductors) to be printed on the circuit board first, and these parts will be slightly stuck by the solder paste just printed on the circuit board, so even if the speed of printing is very fast and the parts on the board will not fall away. But large parts are not suitable for use in such high speed SMT machines, which will slow down the speed of small parts assembly. And the parts will be shifted from the original position due to the rapid movement of the board.

5. Universal SMT machine

Universal SMT machine is also known as "slow machine", it will be assembled some large electronic components, such as BGA IC, connectors, etc., these parts need more accurate positions, so the alignment is very important. Use a camera to take a picture to confirm the position of the parts, so the speed is much slower than High speed SMT machine we taked before. Due to the size of the components here, not all of them are packed in tape and reel, and some may be packed in trays or tubes. But if you want the SMT machine to recognize the trays or tube-shaped packaging materials, you must configure an additional machine.

Generally, traditional SMT machines are using the principle of suction to move electronic parts, and in order to place the parts successfully, and there must be the flat surface on these electronic components for the suction nozzle of the SMT machine to absorb. However, for some electronic parts don’t have a flat surface for these machines, and it is necessary to order special nozzles for these special-shaped parts, or add a flat tape on the parts, or wear a flat cap for thees electronic parts.

6. Manual parts or visual inspection

After assembled all parts by the high speed SMT machine or Universal SMT machine and before going through the high-temperature reflow oven, and we will set up a visual inspection station here and to pick out the deviation parts or missing components boards etc., because we have to use a soldering iron to repair if there are still defectives boards after passing the high-temperature oven, which will affect the quality of the product and will also increase the cost. in addition, for some larger electronic parts or traditional DIP parts or some special reasons cannot be processed by the SMT machine before, they will be manually placed on pcb here.

7. Reflow oven

The purpose of reflow oven is to melt the solder paste and form a non-metallic compound on the component feet and the circuit board, that means to solder electronic components on the circuit board. The temperature rise and fall curves often affect the soldering quality of the entire circuit board. According to the characteristics of the solder materials, usually the reflow oven will set the preheating zone, soaking zone, reflow zone, and cooling zone to achieve the best soldering effect.

For example, the melting point for SAC305 solder paste with lead-free is about 217°C, which means that the temperature of the reflow oven must be higher than the melting points to remelt the solder paste. What's more, the maximum temperature in the reflow furnace should not exceed 250°C, otherwise many parts will be deformed or melted because they cannot withstand such a high temperature.

Basically, after the pcb passed through the reflow oven, the assembly for the entire circuit board is almost complete. If there are hand-soldered parts, we need to transfer to DIP process, and then we have to check the quality after reflow oven by QC department.

8. Automatic optical inspection(AOI)

The main purpose of setting up AOI is because some high density boards can’t be process the following ICT test, so we used AOI inspection to replace it. But even using AOI inspections, there still have the blind spots for such checking, for example, the solder pads under the components cannot be checked by AOI. At present, it can only check whether the parts have side standing issue, missing parts, displacement, polarity direction, solder bridges, lack of soldering etc., but cannot checking the BGA solderability, resistance value, capacitance value, inductance value and other components quality, so far AOI inspection can’t completely replace ICT test.

Therefore, there is still some risk if only AOI inspection is used to replace ICT testing, but ICT test is also not 100% make sure the good quality, we suggest these two ways can be combined with together to make sure the good quality.

9. PCB unloader machine

After the board is fully assembled, it will be retracted to the unloder machine, which has been designed to allow the SMT machine to automatically pick and place the board without damaging the quality for PCB.

10. Visual inspection for finished products

Normally there will be a visual inspection area in our SMT production line whether there is an AOI station or not, and it will help to check if there are any defectives after completed assembled the pcbs. If there is an AOI station, it can reduce the visual inspection worker on our SMT line, and to reduce the potential cost, and because it is still necessary to check some places that cannot be judged by AOI, many SMT factories will provide the mainly visual inspection templates at this station, which is convenient for visual inspection worker to inspect some key parts and polarity for components.

11. DIP process

DIP process is a very important process in the whole PCBA processing, and the processing quality will directly affect the functional for PCBA boards, so it is necessary to pay more attention to the DIP process. There are many preliminary preparations for DIP process. The basic process is to re-process the electronic components first, like to cut the extra pins for some DIP components, our staff received the components according to the BOM list, and will check whether the material part numbers and specifications are correct or not, and performs pre-production pre-processing according to the PCBA samples. The steps are: Use various related equipment (automatic capacitor pins cutting machine, jumper bending machine, diode and triode automatic forming machine, automatic belt forming machine and other machines) for processing.

12. ICT test

Printed Circuit board open/short circuit test (ICT, In-Circuit Test), The purpose of ICT test is mainly to test whether the components and circuits on the printed circuit board are open or short issues. It can also measure the basic characteristics of most components, such as resistance, capacitance, and inductance values to judge whether the functions of these parts are damaged, wrong parts or missing parts etc. after passing through the high-temperature reflow oven.

ICT test machines are divided into advanced and basic machines. The basic ICT test machines are generally called MDA (Manufacturing Defect Analyzer). It’s just to measure the basic characteristics of electronic components and judge open and short circuits issue we talked above.

In addition to all the functions of the basic ICT test machines, for advanced ICT test machine can also test the whole PCBA by using power, start to testing the PCBA boards by setting the program in the test machine. The advantage is that it can simulate the function of the printed circuit board under the actual power-on condition, this test can partly replace the following functional test machine (Function Test). But the cost for the test fixture of this advanced ICT test can probably buy a car, it’s too expensive and we suggest it can be used in mass production products.

13. PCBA function test

Functional testing is to make up for the ICT test, because ICT only tests the open and short circuits on the the PCBA board, and other functions such as BGA and other fuctions are not tested, so it is necessary to use a functional testing machine to test all functions on the whole PCBA board.

14. Cutting board (assembly board de-panel)

Normally, printed circuit boards will be produced in panel, and it will be assembled to increase the efficiency of SMT production. It means several single boards in one panel, such as two-in-one, four-in-one etc. After finished all the pcb assembly process, it needs to be cut into single boards, and for some printed circuit boards with only single boards also need to cut off some redundant board edges.

There are several ways to cut the printed circuit board. You can design the V-cut using the blade cutting machine (Scoring) or directly manually break off the board (not recommended). For more high density circuit boards, it will be used the professional splitting machine or the router to split the board without any damage the electronic components and printed circuit boards, but the cost and working hours will be a little longer.
