We have a job that has through hole components on the top, and one 44 pin j leaded PLCC on the bottom. Presently we put the through hole parts in, run it throught the wave, dispense paste on the PLCC pads, and then apply hot air. Someone suggested we

We have a Versaflow 40/50 and ours is setup like this. We have out nozzle test position set so that in the Z axis you are 3.8mm away from the pin. Used feeler gauge Then you can set your gradient per nozzle. Start with a number then do a wave offs

Hi I have been struggling with boards for high quality picky customer. I am getting flux waves (like splashed - too hard to clean) after wave, where as we are still using Kester 979 (No clean flux, but as we are getting visible marks which looks si

Dross removal is dependent upon the "activity" in your solder pot and the usage of a inert or an "air" atmosphere. The more moving parts that agitate the solder and expose it to air, the more dross. Basics first and then the answers will make sense

Observations are: * Center most lead of the fuse on the top right of the assembly looks like it has excellent solder flow, but this is PTH. From the amount of solder, it must have been wave or hand soldered. * Center most lead of the fuse on the bot

We always have big power modules on the board,they are very heavy,so we use the screw to fix the soldered module,then we destroyed the solder joints.If we screw them first, the board can't be wave soldered. My questions: whether we should use the s

Just started using VOC free no clean in a fully inerted wave. Have problem with one assembly with solder balling. This assembly is single sided mixed and solder mask is UV cured wet film. Other assemblies we build are L.P.I. solder mask and do exhib

It sounds like what you are seeing is leaching of the end cap. You need to check the manufacturer's spec. Many components have terminal barriers, which get a solder plating. Sometimes this plating process is not done well, and the solder plating le
