if anyone has used or has one of these bga rework stations please give me your opinion on them. I am planning on using the sytem for not only rework but also low volume prototype production for hand built 1 or 2 qty pcb's, so ease of use is importa

The DRS systems are far superior. They don't compete with ERSA or Metcal. The nozzle technology, heaters, and software are so much better. I would find a used DRS22C and use it before those other systems. The vision system in the DRS22 is great

Good afternoon, 22C +/-2C, 40%RH +/- 5% is a good starting point. I wonder if any standard requires floor temperature and humidity control. Most of requiremens come from solder paste manufacturers. BR, Pavel.

For an nate measurement method, look here http://www.ipc.org/4.0_Knowledge/4.1_Standards/test/2.4.22c.pdf For bare boards, look to IPC-6012, par. 3.4.4 For assemblies, look to IPC-A-610

I'm not aware of a standard for the storage conditions of assemble circuit boards. Here's what I'd do: * Protect them from damage * Store them vertically * Constant Temperature 22°C +/- 3°C * Humidity Control 45% To 65% R.H.

Never heard of the DRS-22C. I have had a DRS-22 for several years now. Purchased it when we started doing BGA's. The operators like it - good optics (split view), built like a tank, X-Y table easy to manipulate for alignment. I like it because I ca

I am in the process of sourcing and ordering a BGA rework station. I only have exprerience with the OK-Industries (Now Metcal) BGA-3500 BGA rework system. Any experience/input on other comparable systems would be much appreciated (Pace TF3000, Air-

Hi all, We got some bare pwb in our incoming inspecion looked really wrapped. The maximum twist of the pwb we messured is 0.056inch by following the method in IPC-TM-650 2.4.22 C. (The diagonal size of our pwb is 7.5inch) According to the IPC standa
