I have heard that there are problems using immersion gold on PCBs when working with BGAs. Is this correct? Is white tin more suitable?

Hi, We have a white residue, which is visible, and we would like to have the produce clean as it's a PCI card, so users see the PCB. I am wondering if we need to install a cleaning stage to the line for these kinds of products. Can anyone give som

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

As converting our boards to lead-free finish (Immersion White Tin) we decided to change de mask color from green to blue. We thought this would be a good idea to spread the idea so we could easily recognize the type of solder application related to t

We are getting more and more customers wanting LED boards built on White Solder Mask. Well our printers do not get as much contrast between the white mask and the plated fiducial pad, and often the camera only sees white. Other than playing with
