Hi, AJ, In general, the peak PCB temperature is variable depending on the profile used. We try to keep our peak temperatures in line with the paste manufacturers recommended temperatures; ignoring the peak temps for the PCBs. For the peak temps yo

Is there some good resources (.pdfs, websites, articles) that someone can point me to regarding design for bga footprints? I need to brush up on thermal relief design for bga footprints. I got a customer whose bga lands are masking defined on top of

Its a bit of an old beast, it was replaced by SE 200 and is now discontinued (since 2004 I believe). Its a decent unit, but hard to achieve good repeatability on smaller deposits. Its also not reliable on small solderpaste below 20mil fine-pitch. Fai

BGAs are actually easy, but proper stencil design, solder paste placement and oven profiles are a must. Especially oven profiles as this is your only indication that the inner balls have reached proper temp, since you cannot visually tell. If you g

I would say yes. I don't believe that ICT will every be replaced by boundary scan. Now on some assemblies, boundary scan is viable and certainly a better choice considering test access constraints. But ICT still will play a vital roll in the futur

Not to quibble, but I have been a Juki user for over 12 years and starting with the Juki machines 750/760 and all machines since support 8 characters for reference designators. We are even looking to upgrade later next year and they have already con
