Can anybody refer me to a company that does conformal coating removal service of assembled PCBs. They are urethane coated boards and we need to remove QFP devices only. Thank You

We've never involved ourselves in this specific type of effort, but in the past, when removing conformal coat material the supplier of the conformal coat mat material was by-far the most knowledgeable about proven techniques for removing their materi

Notes from an AIM No-Lead Presentation ... Wave Soldering * May require a higher pot temperature than tin/lead: 255-265*C * May require a change in liquid fluxes to compensate for the poor wetting of some alloys and high thermal stresses of the wave

We currently use a tool that we have developed and sell that can provide real time feed back on OSP coatings. With OSP it is a case by case basis on how many times you can reflow or apply heat before it becomes detrimental. Also, Depending on your pr

Hi All, I work for a contract manufacturing and we are having a new PCB to build. The PCB has OSP coating on it and it has been sitting open in the production floor for about 15 days. I am not sure weather it will affect the soldering process or not

| Okay, here's a stupid question. What exactly is HASL and OSP? We are going to delve into this technology where I work and I want to utilize the wealth of knowledge here to make life easier. Specifically, what are the differences, the advantages, di

It will be hard to solder metal that finish by any coating. So you should remove the coating first. You need strong acid to remove coating. After you solder both then you can silder finish esay.

Toluol (toluene). I use it in the solvent cups in my PVA machines to keep the nozzles wetted. We also use it to clean spots where coating is not supposed to be. Techspray 2510-N coating remover pen will also work very well for this.

I haven't had to remove that specific coating before but we regularly remove dow 2577 and other SR with Humiseal 1090 stripper.
