Just wondering why you need to scuff the surface at all, as a decent glue should take to the PCB material anyway. However, it may be a customer requirement, so you have to do it. Have you thought about getting the PCB's made with a rough surface wh

Thank you for your response and information. I don't have any idea on what is Hybrid Circuits but if I will use ceramic PCB does my current SMT line need to change which running FR4 PCB material? My apologized for my queries. Thank you. IR11

I would like informnation regarding this high heat withstanding type material for PCB, also any other types that are compatible. We currently use FR4 but have an application that may require most advanced composition.

We have recently purchased equipment that would probably solve your problem. We are using 1.6mm pcb material 1/3 of which is left unscored. When the pcb is de-panelized there is no damage to any components and we have cut our break time in half.

Hello folks, we would in certain cases run a PCB second time through reflow. I never trusted a board that is reflowed multiple times and I wonder am I really right? Can we reflow boards multiple times? What are the limits? Does it depend on the PCB

Yet another example of narrow focus. "What's the best and latest machine out there, and should I use a technology that's been around for decades." Wrong approach there, Chunks! Think outside the box. My firm, Worldtronics Consultancy Services, In

| We're running into problems with board damage (broken traces, solder shorts) due to pliers and other bizarre tools being used for depanelization. I need some sort of fixture for this. A delrin plate with a slot cut to the correct depth and width mi

I often need to wind a coil for transformers, solenoids, or chokes, & I typically use craft plywood for the ends and a paper tube for the center, cemented with wood glue, or Cyanoacrylate . Then, I usually give it a coat of varnish or epoxy. I am cur
