Kindly advise whether we can use tooling holes if there is no fiducials point on the PCB. Is there any others thing that can use, because tooling holes have it tolerances .

We use an Asymtek C-741 with 2 heads for silicone and acrylics but no convoyer. What type of head and product will you use ?

When using lead free bgas and tin lead paste is almost certain that you will find voiding no matter what type of profile is use. The best thing that you can do is optimize your profile to minimize the voiding.

It is a very simple practice to leave a leader when breaking down a setup. This way the next time you're going to use the reel there is about a foot of cover tape to use. Seems to work in our SMT production area. Max.

for a very repeatable rework srt 1100HR is a very nice machine... alot of $$$$ though.. i recently used a APE Sniper and i thought this machine was very simple but good to use easy to profile, and align BGAs.

We run Panasonic chipshooters, so our small nozzles are not cylindrical. We would use the smallest nozzle we have on our heads which I believe is a Panasonic "MF" size, the same nozzle we'd use for 0603 size components.

Hi Mike, What piece of equipment do you use? I've never heard of using a water jet to route PC boards before, but would like to do some investigating before I buy another traditional router. And why only high volumes?

At my previous employer we ran HSP - GSM lines. Some sites used CIMBridge, others Unicam. We all used UCT52, not USOS, for the HSPs. At that time we had 4796's, 4791's, and USOS 4.X on our GSMs.

I agree with Pete. We use Delmat for SMT carriers. I've never used FR4 but I guess my predecessor did. They didn't hold up very well, but the Delmat lasts.
