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

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

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

Hi all, I have couple of questions/doubts on solder mask, please clarify. Why green color solder mask is popular when compared to other solder mask (RED, PURPLE, BLUE etc.). Are there any performance issues with other solder mask if I use them.

Hi, From a Manufactures choice - Green is the best due to it is the most commonly used mask color in the industry & cheapest. Kind a like Red paint for Barns. For US shops, most only have one LPI machine and to continually switch from Green to othe

Does anyone have experience with different colors of solder mask. I am interested to know if a clear or light color mask is better in the reflow process. Most of the boards we do have a green solder mask. It seems to me that I read somewhere that

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

We have some circuit boards where the solder mask seems clear instead of green on top of some of the tented via pads. No gold deposited during the ENiG process and no solder sticks to it but why is it clear and does it have any correlation to the thi

No, we not sure if your solder mask is LPI. The article we linked was aimed at solder mask application methods. LPI is the most common mask in use today. So, what kind is it? Green tells you nothing. Solder mask can be a variety of colors.
