From Kester's web site: "Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of thr

We like our AOI from Cyber Optics but only use it for process prove out. I would rather have a solder paste inspection system in line. The cost of AOI is killer. A new process is to embed a UV signature between the components pads and when a componen

We use AOI in-line on most our SMT lines, and still getting them for the rest our lines. It has cut down on Inspection Time considerablly, justifing the cost. They do take a trained technician to program and that is a little time consuming, but worth

0.5um(Ni~6.5um) after reflow(data taken in 48hrs).But after performing temperature cycle test ,the former aging rate(from the shear strength ) seems faster than the latter.Why!?Someone call this the 'precipitation hardness',but what actually is it! A

Bill, It is my understanding that in using the Smart Sonic to clean Adhesives from stencils and mis-printed boards it is recommended to have the system up to a certain heated temperature. What is that recommended temperature? Does this temperature

Hi everybody, I need to collect some documentation about BGA rework, in particular I wolud like to know if there are some "theoretical" studies about this matter (for example a finite element model of a BGA suitable to be used to simulate BGA reflow)

I was wondering if there's anyone who can give me some feedback on a product called the Data Pac Reflow Tracker. My company was paid a visit by one of their vendors, but I would like feedback from someone who has used this product. What are its benef

Folk's, I've been running with the datapaq system for about 5 years now. I have been using it on both reflow and on wave, the only issue I've ever found is that you cannot predict settings for wave, but then you can't do that on Kic and I don't thin

I guess the answer to that would have something to do with the distribution of the problems across the various components on the board. [I hear you saying that it's isolated to a specific component, from a specific supplier; rather than being more l
