Get them both to prove their placement rates & accuracy on 0201's, and also guarantee that the machines will achieve this in production. Also get them both to give you a guarenteed placement rate on your most common & difficult boards, then you ca

We are undertaking a project to try to put a rating system to our DFM documents for both PCB design, final assembly, and testing areas. I am wondering if anyone has found a tool that has been used as a DFM rating system so that I may save some time

First all, you must define the specific defects that you wanted to screen out by your AOI system based on its capability, so you can allocate the undetected defects on your other means of inspection methodology. Then optimize your AOI inspection para

Excellent Web OEE calculator... For Ideal Cycle time we use to take Programming Cycle Time but in this calculator it seems you have taken Equipment Rated CPH. For a Given Board & the placement locations the rated CPH is not at all attainable because

Thankyou once again dude. Please Don't mind it. I have one more doubt regarding the Max.Power Rating of SMD Resistor. ---"Is same principle which you told application for Maximum Power rating Of SMD Resistor also"?--- i.e Higher Powerrating is

Good Morning All, We are in the process of setting new attrition rates on SMT components. Initially, we will be setting a rate accross the board for SMT components. We realize that a per part number system is far more accurate but at this time, some

Ramp rate is measured in degrees per second. Max and min temps are not required to to establish "ramp rate". The difference between parts, like I was describing is Delta T. But, ramp rate is a generation from this as well. Most component manufact

We are using a glue and wave solder process for primarily chip components. Our products do not use any fine pitch components. What would an acceptable benchmark for the placement defect rate be? 50 DPMO? 100 DPMO? 200 DPMO? Thanks in advance,

Can anyone tell me how to find information on the protectability of circuit board technology copy rights and what types of royalty rates can be expected. Is there some forum that specifically addresses these issues. Thanks for any info.
