Looking for information on lead trimming after wave solder. Does anyone do this through automated equipment? I know ideally parts would be cut to length before insertion and not trimmed after wave solder but sometimes that is cost prohibitive. When n

I am looking for a faster way to trim component leads after wave solder. We now cut by hand, we have a Q-cuter but stoped using it the blades dulled quickly and left flags. we just got a cut and clinch locator and hope this will solve some of are pro

We haven't built these yet. The customer was in layout at the time and I was looking for any flags from others to determine if I should have them change the layout as I've not seen this before. From your response and others that I've received, it s

I did have my solder analyzed and it is clean. The Hollis preheat coils are a bit hard to control but I have measured the board top side and I am getting a temp of 105c just before wave contact. I would like to move to a spray fluxer but I am going

Is it possible your board is warping and skip plating? Have you run a lev-check? What does your contact patch look like? Do you have ice cikles (spelling???) or solder "flags". IF yes, your flux is consumed or nonexistant. What is your dwell time

Hi Rob, Yes I agree with everything stated. Lots of things can cause this. I have gone over everything mentioned in your response. The thing is, I could do a simple drag and had no issues, then a few bridges then more. So I have checked everything, m

| It has been known that sufficient cooling after soldering is important in order to get a stronger joint during its solidification stage. And it has been so much emphasised with reflow oven. But, why many models of wave soldering machine do not come

Just a thought.... Some Fluxes require temperatures upto 260F (127C). Are you using water based flux or solvent (alcohol). I have noticed that many wave machines are NOT capable of preheating adequately when using water based materials. This can
