You're looking for quick and affordable ways to paint PCBs. You're right to check if the paint won't conduct electricity—make sure it's non-conductive. Consider using spray paint or screen printing for efficiency, or apply a thin layer of conductive coating if needed.
Apply with a paintbrush and expose the rams to sunlight. Consider using a nonconductive surface if needed. Other possible techniques could include UV exposure or specialized coating methods.
UV solder mask serves to shield the copper traces on a PCB after repairs. It’s commonly applied during refurbishment or maintenance. For curing, opt for a budget-friendly UV lamp instead of sunlight—this reduces the risk of dust or debris interfering. Remember, always proceed with caution and consider local availability.
You're considering wrapping your valuable semiconductors in insulation? That might not be the best approach. If you choose to add color, ensure it doesn't touch any electrical contacts—like PCI slots, M.2 connectors, SATA ports, USB, audio headers, or power connectors. Better to skip it altogether. You'll appreciate it later!
I focus on function rather than style. I’m painting the rams black because I want them to stand out when selling overclocked bare PCBs. With an open-top heat spreader, visibility is key, so a decent look matters. I probably won’t bother with MOTO painting unless there’s a clear business reason. Aesthetics aside, I won’t waste time on risky shortcuts—unless I test them first and they perform well.
I think it's a bad thing to do. People that buy computers from you will think you're scamming them when they realize the ram sticks are from factory that color. But if you want to keep going with this... maybe try plasti dip paint , it's paint with some plastic/rubber particles in it ... here's an example : https://www.amazon.com/Performix-11203-M...SU3QW?th=1 Use kapton tape or some other protective tape to cover the gold contacts and then spray from a few inches across the whole stick - when it dries out you should get a matte layer of paint, which should not be conductive, but you'd have to test. I'm also thinking acrylic paints, but not sure how conductive they are. You also have the option of coating the sticks with a very thin layer of conformal coating, it's a transparent layer that insulates exposed contacts. Basically you'd cover the surface of the ram chips with kapton tape or something (because the surface needs to remain clean to make contact with the ram heatsinks), and the ram gold contacts, then you'd spray the whole stick to give it a thin layer of conformal coating, and then you remove the tapes. I'm not 100% sure, but you should be able to paint over the conformal coating once it's fully dry. examples of conformal coating using silicone https://www.digikey.com/en/products/deta...S/10440570 or https://www.digikey.com/en/products/deta...12/5251702 using urethane https://www.digikey.com/en/products/deta...S/13590618 UV solder mask would also work to cover exposed pads, but would look ugly if you cover surface mount resistors and capacitors on the stick with it.
We plan to market overclocked RAM by offering bundles that include both the CPU and RAM together. This way, customers can ensure compatibility and performance.
I’m planning to build open-top heatsinks from aluminium strip rolls. The timing and branding will be rough, and even with UV solder mask it won’t be flawless—this suggests it’s just bare PCB. I’ll test it on a Z77 + Pentium (wait, the Z77 hasn’t arrived yet) and adjust the frequency to around 66 MHz or similar. Please note the disclaimer: speeds above 2200 are for newer than X58, below 2200 for X58, and older systems can go up to 2.1V. I’ll ask users about their specs and tweak the settings accordingly. If it’s a low-quality OEM or non-OEM board, I’ll settle for 1600/1866 with lower clock speeds. For OC chipsets and non-OEM boards, I can push up to 2200+ (XMP). Newer than X58 only supports up to 1.9V XMP, while older models cap at 2.1V. I’ll provide settings for 2.2 and 2.46V depending on the IC, but not fixed presets—just adjust as needed if performance drops. If minor CPU issues occur, it might be due to a defective die; otherwise, they may have accepted the risk. Anything missing? I can make cheaper versions myself, though the only decent options seem to be closed-top HyperX heat spreaders, which aren’t ideal for airflow.
