Hi, We have software tool, called TopoQC, that displays topologically CAD view with failures and calculates solder points by one click. Also, you can calculate DPMO & Six Sigma values on the same screen. You can read about it on our website: http:/

what is the technology? Is there fine pitch, double sided, number of layers, lead free? If the pcbs are not of the highest quality you may be set up for failure with no clean process. Couple things to look at is your paste flux content versus medal

I have seen similar things happen with over etching and bridging but frankly the most common mistake that gives us grief is a failure to use the component manufacturer's recommended land pattern and/or aperture designs. As opposed to generating a n

Good Morning Everyone, This whole lead free thing has really stirred up the hornets nest! I agree that it doesnt make any technical sense to replace a cheap toxic material for an expensive toxic material that costs more, is more expensive to process

Dear Ing, Have you analyzed why some RF device aren't operational after washing? An assumption is that failures are related to the ultrasonic energy applied. Other possibilities are for poor rinsing, poor drying, inadequate washing on those failed

We currently have 2 M1 systems. Our false call rate has never been has high as you suggest. There is something wrong with your program and/or inspection algorithms, as you probably already know. You should be somewhere between 1000-1500 vcpmo (fal

We need to be careful with product to avoid introducing a new failure mode, namely corrosion and dendrite growth, especially those running no clean processes! In addition to heat (reflow, wave and some selective soldering processes) killing the vi

There's just about 4 beezillion companies that give solder training. Some are: * BEST Rolling Meadows, IL 847-797-9250 Bill Westmoreland (bwestmoreland@solder.net) http://www.solder.net/ * Circuit Technology 340 Raleigh St Holly Springs, NC 27540 (

I have experienced this directly in SMT and wave solder. Fillet lift (can) be a direct indicator to lead enrichment (but its not the exclusive symptom). Lead enrichment in smt joints reduces the interfacial strength shortening the time to creep f
