We have two selective wave machines that run all day every day. We're pretty high mix. Almost all products don't require preheat but it is nice to have in case you need it on something dense. Good reliable flux sprayer is important. Software that

For selective soldering I would first look at the alloys your products require. Do you run tin-lead, lead free or both? If you run (or may run in the future) two alloys, then look for a machine that has quick change solder pots. Secondly, do your bo

I feel like such a "nit-wit" now. Diversity is what makes America great. Freedom of choice. The last I remember Multitronics is a UK based company ..OPS thats right Multitronics was purchased by a Bermuda based company... silly me. Let me guess..Y

thomas, why isn't it process control, you cant just think that because you've set up your machine properly ( pot temp, wave height, pre-heat etc etc )that everything is going to be ok, there are other factors that you wont find with wave riders or

We are increasingly being asked to store components for longer and longer periods which we know through experience leads to reduction or total loss of solderability of the parts. 1) What is the industry accepted shelf life of tin/lead plated compone

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

Thank you all very much for the responses. The solder is eutectic and the problem, as far as I can tell, has been around before I was here, 2+ years. The flow machine is a treiber with 2 bottom preheaters and 1 top. The solder pot temp is 500F +/-4F

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

I recently witnessed a process in which the solder pot operator used Techspray WSOL water soluble masking to cover the areas around a connector that was to be soldered on the solder pot. He did not wait for the WSOL to cure. He soldered immediately.

If the mask is not cured and is coming off in the pot I don't see how it is protecting anything. If you want to mask something fast you need to use tape not liquid mask that requires cure. My $.02.
