Hello, I'm a new member to the forum and I am trying to locate some information and companies in a particular sector of the market. I'm trying to find the people that supply die cut components, such as adhesive sheets for circuit boards, foam pads

We have a situation where our customer returned a device (BGA) with a missing solder ball. The process is Copper-Nickel-Gold-Solderball. EDX revealed that no trace of gold nor solder material (lead-free balls). Could poor Au plating/adhesion cause

The Luxeon probably are the brightest available. I say probably only because this changes every day. The Luxeon require special mounting as they must be mounted to an aluminum cored PCB with thermal adhesive and then the leads soldered to the PCB.

Has anyone tried to use electrically condctive adhesive rather than solder to connect the leads on 5 watt Luxeon parts? If you design the board right to dissipate heat, when you have a bunch of them in a tight array, even with thermal relief on the t

We are experinecing adhesives left on the boards after running taped boards for placement verification on NPI. We've been using 3M double sided (333) tape for over 15 years. Any other suggestions on a good tape to use? This may be a quality issue

Assuming you mean paste and not adhesive, we use both wet and dry with vaccum. We can control the solvent thru the software for each job, so no solvent sprinkling thru the stencil. Never head of corrosion on stainless steal, but then again I'm sure

Wow, these are still around? Don't go IR, especially with these units. They are very inconsistent. Maybe for adhesive, but I wouldn�t try reflow with them. Yes, you can reflow with them, but this model of oven will constantly change on you. I

Well, most of the capacitor are thru hole, then pcb's goes to adhesive process upsidedown to continue SMT process in which , maximun tempetarure is 120�, so temperature is not problem. About SMT capacitorS, I will check temperature specs before mount

Thanks everyone, I have found your postings very helpful for reflow ovens and intend to review my reflow calibration and validation, but in this particular instance I should have been more specific. We use the non conveyorized type of oven (Ten

This is an issue that we are seeing a lot! It used to be that the primary-side (component-side...top-side) had most of the active components. It was simple: reflow bottom first. Now, we are seeing both sides of the assembly having the same amount of
