3D xray

Electronics Forum | Wed May 30 17:21:25 EDT 2007 | troyboesch

Pretty much everybody does functional or system test at the end of a printed board assembly line. In-circuit or MDA test hits most complex boards. But, 3D xray is being pushed by Agilent, Teradyne, and TRI. No fixtures and a high call rate for sol

We are looking into purchasing a Falcon ICT/FCT from Digital Test. Does anyone have any experience with this company or the machine? 1) How would you rate their technical support? 2) What are the functional test capabilities of their machines (pr

To date we are a small niche CM doing prototype and small runs. Any testing we do now is purely functional tests on the pcb ass'ys. In some cases the hardware and software is supplied by the customer, in most cases it's one or the other. We want to e

Flex cracking under the terminations is generally regarded as one of the primary causes of failure of ceramic chips. If you can see cracks in the solder joints from board flex, those chips are certainly strongly suspect, and you must assume there is

SMT Design Issues for 2225 Capacitors in High Power RF

We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t

ICT is generally a manufacturing verification test. Coverages vary depending on the board. I've run lots with as low as 25% coverage on the board (but produced 98% FPY post board assembly). Functional test is exactly what it sounds like. Checking

| If i want to set up an assembly line, what would be the approximate cost for testers? Appreciate any replies. Yuan Yuan, Expect to pay about 300k for a decent ICT system. This price does not include fixtures. You can probably find something chea

Solder void underneath the mosfet

Electronics Forum | Thu Mar 25 11:30:33 EDT 2010 | Sean

Hello Rajeshwara, If not mistaken, the 25% solder void specification is for BGA...As I I as know, no specification given to mosfet component yet..I think you are right, I need to look at the stencil aperture in order to reduce the air trap underneat

Q1.� is it mondatory to test all components and paths in the PCBA; and check all soldering joints? A1. Nothing is mandatory. You do ICT to prove some component functionality and check manufacturing process. ICT test coverage is driven by factors i

Re: Why does everyone want to x-ray BGA?

Electronics Forum | Wed Jun 30 20:09:07 EDT 1999 | Mark

| Hello Ya'll, | I've got what may be a silly question, but why does it seem so important to everybody that you have x-ray capability if you're thinking about doing BGA? | I know what most people will tell me; "Steve, that's a pretty silly qu
