Yea, I'm still here.....sigh. Got bridging problems. These assemblies are SMT topside, then go thru wave for thru-hole components on topside. These assemblies have many, many, many vias VERY close together. We have a problem with solder from the wa

| | | Does anyone have any information on stencil aperture/pad ratios for noclean solder paste. In the past I have experienced severe solder ball problems when using the same size apertures from aqueous products as I do with the No-clean products.

Hi, We are encountering a shortage on our parts and our purchasing said that the parts, which is in PLCC packaging, is hard to order from the local and international market and we can only get them in QFP packaging. Now the problem enters here. Our P

Hi John, we had one shot with silver coated PCBs. With "no clean" and no changes in process parameters ( we had no input on necessary changes from the boardhouse ) we encountered wetting problems in the first reflow soldering process. Later it was s

I searched the archives and couldn't find anything specific. Our designers would like me to wave solder an SO18 on an upcoming product. My IPC standards have land patterns, but no recommendation on wavesoldering. This is a higher pin count than we

If your solder paste has forsaken the pads and gone to all the work of climbing the leads, it�s because the leads are much warmer than the pads. Some like it hot!!! We talked about this on SMTnet within the past 6 months. Please check the archives
