HI, i work for an EMS company and i got a few remarks on the solder mask question. In the manufacturing of PCBs there should be no difference if they use other color solder mask, but in the production of electronic assembly it could make a difference

I did not change my mind, I just said that we sat down with the manufacturer and showed them the 3-4 different color PCBs for one product. They agreed that it is not acceptable... and supply us only from one of their sites. (the different manufacturi

Sorry, if my first comment was a bit offensive against PCB manufacturers (it was not really intended :( ). We have already discussed the above mentioned issues with the manufacturer, and they stated, that everything is within specification... (and y

Hi Konrad, Nothing is ever Clearly one persons issue. Color differences could be caused by many things. 1) Being the solder mask is a two part mix, there is never a 100% guarantee that the color will be the same from lot to lot. 2)the Manufactur

konrad, Here are a couple of things that can affect color. 1) Material color is the major, 2) Matte green from Enthone would be different in shad than Matte green from Taiyo. 3) Solder mask is two parts, One the green mask, two the hardner, having t

Aw Dave - you guys are so fashionable, are the dark green and red combos seasonal? caramel brown like a Pale Ale? I once heard that the green was chosen because it gives the best color contrast for white silk screens. As for color reflecting or abs

Emil, Part of the problem it sounded like is that the color was not clearly defined as light or dark in Matte or gloss. Your example of car paint would have the same issue if you just ask them to paint your car green. What color of green would y

Caramel is more like a amber ale than a pale ale, although not as redish as the amber. Actually, it's more like caramel. It is real brittle and scratches easily. If we built the board more often, we'd change it to a more familiar material. Naw, n

Hi Konrad, I would suggest you include a clear mention of your requirement towards mask color as a "Special Note" in PCB Gerber / PCB drawing, for ready reference by your PCB manufacturing during fabrication. However, slight changes in color shade co

People use green soldermask because people use green soldermask. In the 1950s, the US military selected green, because they liked green better than other colors. So, here we are. We believe the performance of red and blue is comparable with green. T
