What is the industry standard for wave and selective solder PPM defect rate for a world class facility, any responses are appreciated.

Also Try: http://www.airliquide.com/en/business/industry/electronics/expertise/tech_papers.asp you can also search the airliquide site for "PPM" once in the electronics section Cal

1. For laser machines, there should be setting for Z - at what level you should cut measure the part in Z axis. 2. Check all calibrations are in place and passing 3. Check resistor package setup in the software - all dimensions

| Hello, | | I will be evaluating and qualifying two equipment types. The first is a fountain soldering device. I need practical advice on all the stuff you guys and gals know about as good, bad, ugly, best applications, setup, limitations, and all

Hi Bert, For your second issue, are the tools well lubricated? If not the Midas head can fail to grab the tool and can generate the z motor error. Doing this followed by a base-centre level measurement should resolve your problem. Steve

U may check your profile ramp rate. The flux may evporated and look like cold joint

That is possibley CTE mismatch between QFN and PCB material, the thicker PCB the higher fail rate.

The first thing that I would do is contact the smock manufacturer and ask them for advice on testing the smocks. ESD FROM A TO Z 2nd ed. (Kolyer) states that: smocks should have a resistivity of less than 10^12/sq and must not shed steel fibers.

I was wondering if anybody could tell what web sit rates the equipment in regards to speed? I was there before but forget the address. Thanks,
