After analyzing the pictures I don't think the solder balls are caused by the solder mask. If the problem would be solder mask related the solder balls would only show up on the solder mask but there are also solder balls on the plastic tabs. To me i

Are your voids looking like blow holes also? Is this only occurring on the solder joints of the Thru Hole components and Via's? Or does this happen on SMD pads? My experience is that we have seen this but only with some of our older PCB's which are

| We are wave soldering a board having 24 similar thru hole connectors on it, using a wave soldering pallet. The problem is that one particular pin of connector in around 6-9 connectors get excess solder on the bottom side. I have tried all the par

If you havent already resolved the issue. I would recommend running a wave profiler and see if you are actually getting the same thermal profile in each machine. Generally speaking you need to run different preheater settings for different brand wave

I suspect the problem is a surfactant issue in your flux. I have seen where boards are fluxed, hit the solder fountain and come out like they never touched the solder. There was an inadequate surfactant between the solder and the PCB. I know you

Kinda along the lines 'if it comes we will build it'. Perhaps you can assemble it, I've not done it, but a question to ask a bit earlier is - should we. Check the specifications for the component, published by component vendor. Most of them really

Dear all: I need to know why do I find a lot of solder balles every where on the solder side of my assemblies after coming out of the wave solder machine. How can I avoid this? Thanks Hany

Hello! I'd like to now if you have similar requests from your customers as we have that we are not alloved to manually repair solder joints after reflow or wave soldering process? Regards!

You have incomplete plating in the through holes would be my bet, baking will not solve, nothing will, at least that is what I have found except a lot of hand work and frustration, have your PCB house perform cross section at affected area in your
