I am having cleaning problems when processing PCB's which have TAIYO solder mask on them. After processing, hand soldering and cleaning, a sticky residue is remains, resulting in a cosmetically poor finish with tide marks etc. Other solde

I�m not clear on the problem. What I get: * Your fabricator did not deliver the product that you asked for in your purchase order. * Pad. Land. A portion of a conductive pattern used as a termination area. Metal surrounding a hole on a printed ci

We are in the process of getting into no-clean paste and fluxes. One important issue in this is sodler balling. I have heard some people say that having a matte finish would help in having lesser solder balls and that the solder balls would not b

Is the peelable mask (put on by the boardhouse) flat on the surface of the pcb? If so can you tell me the material name, so maybe I can find a picture? We have to print adhesive on the board, so the mask has to be flat. That is why Kapton from the b

PCB designers specify the application of solder mask [eg, varnish, solder stop mask, solder resist, etc] to fabricators to reduce the potential of bridging between two conductive traces during assembly soldering processes [eg, wave, reflow and hand s

i had a problem here, during the wave soldering process, we apply a water soluble mask on the gold finger to protect it from contamination. But after washing, there is still some mask left on the gold finger. Can anyone pls advise is there any pa
