We doubt that entrapped process chemicals cause under-etch. Over-etch maybe, but not under-etch Under-etch is an indicator of improper process control/improper chemistry during etching. Under-etch can result in bridging between traces, resulting in

I'm not familiar with SPC Plus. I'll assume it's a "statical process control" system. We use the SPC data collected by our YesTech AOI system, together with a custom, web-based reporting system for process analysis and defect reporting. I am actually

I'm sure if it was as simple as that, the AOI technology wouldn't exist. It does however so there must be a need out there for it. Perhaps companies have taken your advice of "save money" to a level that now requires excessive detection controls to b

I am the AOI control programmer on Orbotech Trion 2340 who deals with the component librarys, shapes, programming and tuning the AOI. Trion has quite good learning curves I had an idea make own shape for every PCB or gruop of very similar PCB's and o

Depends on how the heat sink is located above the component ;-). However, short circuits can only be controlled if the AOI is equipped with side cameras and the view of the connections is clear.

Greetings. I have noticed quite a few postings lately to the effect of "hi, I want to be a SMT pro and make circuit boards, help me". Try to understand why folks on the forum are cringing at your proposal. All of the feedback I have seen regarding yo

Dear Abhishek, I too got the opportunity to investigate this defect Lift lead for SOT. Lead lift in IC, and SOT can occur due to various reasons. Here are some possible reasons for lead lift and ways to avoid them: During the assembly process, mecha

I agree with 3DAOI.com, in that you should be looking at Cyberoptics. They have a great product if you MUST have both of these processes in line, and if you must have 3D AOI. If you are willing to go offline, and want to get both AOI and SPI in one

We are in the process of considering purchase of an AOI. Before doing so I would like to know if someone, with experience using an AOI in production, can share pros and/or cons. We are looking seriously at the Photon Dynamics 7550 (Previously CR Te
