PCB Manufacturing Process: All You Need to Know

Creating a printed circuit board (PCB) is a systematic process that begins with meticulous design and material selection, crucial for ensuring functionality and durability. The initial steps involve the application of a thin layer of copper over a substrate material, typically a fiberglass substrate reinforced with epoxy resin and glass fiber, which provides the necessary rigidity and electrical insulation. This copper layer is then patterned to form conductive areas that will eventually carry electrical signals.

The layout design process utilizes advanced CAD software for precision, ensuring that the conductive paths and component placement areas are accurately defined. Once the design is finalized, it's transferred onto the PCB using photo reactive chemicals and UV exposure, a process known as outer layer imaging. This method allows for the precise alignment of layers and the creation of intricate circuit patterns.

After the design transfer, the excess copper is removed through a careful etching process, leaving behind the copper traces that form the circuitry. The PCB then undergoes a laminating process to apply a solder mask, a protective layer that covers the entire board while exposing the areas where components will be soldered. This solder mask application is crucial for preventing short circuits and ensuring the longevity of the PCB.

Following the application of the solder mask, a silkscreen printing process adds labels and markings to the PCB, aiding in component placement and board identification. The final step in the fabrication processes involves applying a surface finish, such as tin plating, to protect the exposed copper and ensure a reliable soldering surface. Other surface finishes like HASL (Hot Air Solder Leveling) or ENIG (Electroless Nickel Immersion Gold) are also used depending on the application requirements.

Throughout the PCB manufacturing process, precision is maintained through the use of technologies like CNC machines for accurate drilling of holes that will accommodate electronic components. Each part of the PCB fabrication process, from the initial design to the final surface finish, is critical to enhancing the PCB's electrical performance and longevity.

The final stages of assembly involve the placement of components onto the PCB, often by a contract manufacturer specializing in PCB assembly. This is followed by soldering, which can be done through various methods, to securely attach the components to the board.

Rigorous electrical tests are conducted to validate the PCB's performance, ensuring that it meets stringent quality standards before integration into electronic devices. These tests verify the integrity of the conductive paths, the correct orientation of components, and the overall functionality of the PCB.

This holistic approach underscores the importance of meticulous craftsmanship and thorough quality assurance in producing reliable PCBs that power our modern gadgets effectively. Each step, from the initial plating process to the final surface finishing, contributes to enhancing the PCB's electrical performance and longevity, making it a vital component in the electronics industry.

ACT 2 "You're... me?" "That's right, stardust!"

You know I've been drawing Loop as their Siffrin form so much that it's got me thinking. I've read and seen so many fics and artworks of Loop eventually getting back to looking like their old self, but I don't think I've seen any so far of Loop already being a mirror copy of Siffrin. So uh, yoink?

ISAT AU where the game plays out the same way (plot-wise at least) but Loop looks like Siffrin the whole time and while Siffrin is extremely perplexed that there's another him, he's still gotta accept their help because how else are they supposed to escape the loops? Good ol' Loop is here to help, helpful friendly Loop!

Siffrin is going through it still but Differently.

Trying to remember how to draw the Deltagang (I never knew in the first place)

[onethousxndvoices]

took a break from my main projects to do some visdev practice. have a line up for a layton fic that'll probably never see the light of day

I am begging on my knees that Tumblr posts this. It has no audio but I cannot send it from my computer to phone and I want it archived lmao-

My not so close to cannon hc is that, after getting into college, Clarrise gets a car somewhere.

Some people assume she got it from her mom, or that Chris stole it for her, but the truth is she actually got it from Ares. Which means you can pretty much imagine what kind of car that is. It’s also unconfirmed but some of her brothers insist the car is magical in some way. Leo tried many time to convince her to let him see what the cars system is like on the inside, but was turned down in a not very nice way.

Very quickly she becomes the ‘carpool friend’ and also the one Chiron tasked with picking up demigods who go to school in NY at the end of semester and get them to CBH, there’s very few of them so she doesn’t mind, +some of them are mortified at the thought of getting in Clarrises car because of how fast she drives. The fist time Percy and Annabeth asked her for a ride, Percy said he was glad Ares didn’t offer to drive them to Vegas that one time, and Annabeth asked if the car really is magical, because she was convinced they should’ve crashed like ten times.

The only two people who will get in the car willingly and without any reason are Chris and Drew. Clarrise picks Drew up from school on regular basis whenever she comes to NY, and they just drive around. One time Sadie saw Clarrise picking Drew up and was convinced Drew was being kidnapped, the only reason she didn’t call the police was because she was stopped by Annabeth who introduced her to Clarrise.

Super honored to have worked on this interactive visual novel Doodle celebrating geographer and cartographer Marie Tharp!! She has an incredible story. This project was also done entirely in watercolor! It also as voice over by three contemporary female scientists working in geology and Earth science!  [Check it out here.] Many many thanks to Alyssa Winans who painted the majority of the interactive scenes, that inherently needed lots of iteration. Also Anthony Irwin who did the UX/UI, and many things that were not UX/UI. ALSO our engineers Gemma and Jonathan who put Everything together, and even managed to teach us how to do some basic eng things so we could have more control. It has been one of my favorite things I’ve worked on!

honestly i thought surtr was like some sort of hidden arknights boss or an ex-villain or something but she's just a passive mall goth lounging around and eating all my damn ice cream

Because I was really bored here is a Rodent playlist I made,

It’s mostly from Vincent’s point of view, and it follows no true order but it does set a vibe.

Have fun with it!

I actually drew this ages ago when Dead Plate came out, but I was in my self-imposed hiatus. You get to see it now :)

It's pretty rough in terms of outline, but Rody is just so fun to draw. He is so silly to me. Also so silly how he hates bitter food and Manon can only ever make bitter food for him. And how the grilled hanger steak is bitter, isn't that so funny haha-

I too fell for the dark Gordon Ramsey (Timelapse + Music under the cut)

Was listening to this while drawing, the songs hit the vibe check lol

[mothscotch]

i love redrawing things i made like a month ago and it looks like 10x better

speedpaint under the cut

i reuse my canvases so its cut to the new drawing :3

i tried something new this time and it was so fun
