Sorry, I have not read the article. However, I do have five years experience constantly tweaking an AOI system that ran ONE product! The strength of the machine was solder inspection. The biggest problem was component color variation and shadowing

Hi BJ, Everyone's favourite answer...it depends! If the volume if large, masking boots will save you both, time and money in the long run. Custom boots are relatively expensive to buy, but they pay themselves over time by savings on masking tape. ma

First of all, do not use kapton tape! It tends to cause a dewetting effect around the tape. A call to Humiseal will explain why. There's not really a blanket answer to your question.... Removing cured liquid mask can often result in a fillet ef

The 2060RE model that I have can do an 18"x20" board. I think the Mydata can do larger. Juki did tell me that next year they will release a machine that will do larger boards but didn't specify on how big. The 2060RE can do 0201 up to 74mm square

We will be receiving our lead free wave solder machine soon and I have been doing a lot of reading here. I've seen many dicussions about SAC vs. SN100C for wave applications and am leaning heavily towards the SN100C for my process. I haven't seen any

I can't believe this is the first time this has happened, but anyway..... We have a turnkey job (customer provided only the bare boards) that included testing with their system. One board failed, and we found damage (a short deep gouge) that seems t

I have used, Siemens, Juki, Fuji, Universal, and Assembleon. All of them can do the job, depending on the machine mix selected. I personally prefer MPM screenprinters, after using both DEK and MPM. BTU, Vitronics, Heller, and Ellectrovert all make

Marc, Topside temperature is one of the most critical parameters for a successful solder process. Temp stickers are OK to use but won�t tell you the temperature in tight areas. The temp gun like Jay suggested is what I use as a quick indicator. (Rayt
