Hi everybody, First of all, to have process under 100% control you should have AOI after every active process in the pcb assembly line : - Post printing (2D or 3D Solder paste inspection machine); - Post reflow; - Post selective(wave solder). It i

Hello Peter, In reflow, running a profile and collecting thermal data does not necessarily make it easy to calculate and determine machine capability. On the contrary to your desires of simplifying the process, determining machine capability on an ov

We are a manufacturing facility of ruggedized offroad electronic control systems. We are looking for industry standards/benchmarks we can use to compare with other manufacturers with regards to our DPMO rate for our SMT process. We would like to kno

Hi, We have clients who developed a similar model and even some of them turn it on for some time. The problem is the high cost of ongoing maintenance. What is true, the system allows to study weak places of pre-production and our customers were able

| We only do rework with SMT components or a small amount of SMT work. We are having a hard time keeping the components safe throughout the handling process of removing one or two components, and issuing them to an operator for processing or inspect

We are in the process of settign up an SMT line with conveyors. When planning for a 4ft conveyor (or 2 or 3ft for that matter), how mush space should I set aside for this? My boss is telling me to leave 4'6" for a 4ft conveyor. I think this is too

This is a general question just to see what people may be doing to control the stencil printing process. I am new to the stencil printing process and as the subject line states I am looking to set up an SPC plan for my MPM UP1500. Now I have a few
