I just purchased some PACE ST-25 systems for basic soldering and they work great. It was a deal at $155 each and they heat up FAST! Tips are around $6 each so the whole system is affordable. A step up for rework jobs would be the Metcal MX systems.

Thanks for your reply! Have you tested the torque meter yourself? I have asked our supplyer if they had any but the answer I got was that they should check with Fuji, and that semes to be a slow process... We do mouthly mainteness on our highspeed fe

Hi aj, Pete is right, there are several variables that can affect your quality when it comes to stencil design. A good idea is to have a stencil made with various designs incorporated into it. A lot of engineers like the reverse homeplate design.

"Although some lead-free pastes performed adequately and newer pastes work better than earlier formulations, this detailed experiment confirmed that tin/lead solder pastes wet back to PCB pads better than lead-free solder pastes. Therefore, a more ac

I use a Liberty Bandit brand hot air rework station and have placed 676 ball BGA's with very few problems. All of our products are now RoHs. They have good product support and easy to use directions. I think this unit runs about 15,000 or so. Good lu

I would also encourage you to talk to some brokers. If you just need something to cut them off the tape, I have a pile of that stuff (no-I am not a broker)and so does everyone. But if you need to kink leads, it will be expensive and in most cases the

I am guessing Theresa is saying when that some SMT parts are soldered (not glued) very close to some PTH parts. So close that they can't effectively mask the SMT parts and have an opening for the PTH part. At the company where I work, we've been tr

Is anyone using standard FR-4 material for ROHS? All I have ever seen to indicate the need to go to a high tg/td board is that the material may fail after repeted rework. I have a customer that is trying to use IS-410 and it is causing electrical pro
