I'm not in assembly, but I do know of a technology called Sipad if you are only looking to do small batches. They pre-apply the solderpaste to boards with a light adhesive, which allows you to hand-place components, even micro BGA's and fine-pitch Q

Hello All. First time poster. I need to design a PCB which will include a Bumped-die type chip with 6mil (152.4 um) pad pitch. I read somewhere that FR4 type board may not be a good choice for such small footprint. I have not had to deal with board

What kind of cleaning method you recommend for PCB - double side SMD (fine pitch and BGA components) and THT elements (PCB are for microwave application!!). Process technology no-clean.We have to remove grease-fingerprints, dust etc. It is low volume

A good paste will print fine up to 5 in/sec or so. They key, as mentioned, is to get the pressure right for a given squeegee speed. If the squeegees aren't giving a clean wipe then you'll see huge variation in print volume which can lead to shortin
