JC: Seen this before, many times. We fixed our problems at the co I work for by giving a packaging specification to our purchasing dept. Took some work but the payoff was pretty big. This document includes such things as orientation,pitch,tape type

Are you working for an OEM? If so see if you can get your engineering department to change their "zero orientation" for the packages. At one place I believe the CAD department called them "G codes". What was really bad there was that one shape had

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

| Is there a standard rule/guide for the orientation of pcb's in a panel for panelised board (specially for routed panel). | i often get this question from peeps here and i kept telling them that it depends on how it affects the process. | thanks and

| | | we have just started wave soldering passive SMT components and through hole. We are having trouble with voids on the SMT components. It is very random, but effects a lot of TSOT's. We are using an electrovert with a chip wave. Are there any

A.O.I. machine in use by my company is made by Cyberoptics and is called a Kestra. It inspsects boards prior to the reflow oven and highligts missing parts,mis-placed parts, wrong parts( by looking at any text on the device that you define, or by ori

Thank you for your response. I have been told that x-ray strength is finding solder volume and pattern root cause defects, and will catch a high % of them - opens, shorts, insufficient solder, and missing components(shape of solder on pad w/o lead i
