What is the purpose of glueing it? If it is glue the bottom side parts followed by reflowing the top side parts followed by wave soldering the bottom side parts, then it's easy to measure. Hold the board with the 0603s facing down. If they don't f

Jorge, The basic thumb rule to measure Adhesive Strength remains as bonded Chips at Post Reflow should not move around or misplace when Your Thumb Finger try to do so which called as Thumb Force Test. However as Dave stated, there are various Stre

Use a push/pull tester. I use an OBA inst. works Ltd. tester. Just because mask comes off with bonder doesn't mean bonder is strong or cured right. Mask can be weak in between pads do to area size. Do it right and you'll know for sure. To many people

Thanks for the info, I will check tolerances and the quadaling option. As an update I ran this past week and machine was arround 5% for a very small lot size, for a larger size lot it was less than 2%, Now I know it still higher than our newest machi

I think you should first learn the principles of the circuit, understand the components and understand their function, skilled operation pcb design software. There should be a lot of such tutorials on the web, and you can learn from yourself. Of cour

It means the machine places another component, no missing PCBs are built. As an update I have measured this % in the newest machine and it is below 1%, but in our worst machine (old quad) it is as high as 9% for a small batch of 10 boards (~15 comp p
