You may not be getting enough exhaust pull, so the cooling modules over temp. Try swapping blower motors to isolate that before buying one. STANDARD AIR OPERATION: - Load-end: 150 cfm (255 m3/hr) at the 4� (102 mm) stack (minimum requirement) - Unlo

Most ionic contamination testers prompt the operator for the current concentration at the start of each cycle. The normal concentration is 25% DI Water and 75% IPA. Although most machines ask for the current concentration, concentration adjustments

What the other user was talking about is correct, converting it from gerber to machine cad. It is hard explaining programming SMT to a new user unless shown by another experience operator. I am also getting a topaz x pretty soon and I'll try to hel

We see this fairly often. It doesn't affect solderability. Our analysis makes us think this coloration is copper. The reason copper appears on the surface may be that heat cycles increase the thinness and porosity of the immersion silver [IAg] coatin

Anyone have an 'easy' solution for reducing PCBA handling damage. I'm fighting low level chipped, scuffed and broken-off SMT parts. The damage is spread out across different areas of the assemblies. The assemblies are double sided SMT with 0402's

The only easy solution is not to handle the boards. Purchase true double sided reflow lines. Buy automated magazine loading conveyors. Check machine board supposrts. Are you sure it's from handling? We found it was 50/50 between board handling

Exsydeco, I speculate how You did not look forward to claim Your due Pay Checks for whopping 120 Days !!! It would've been much better if You associated with Local Administrative Bodies in Italy however You was there for long 8 Months and knew what

I don't have CircuitCam, I'm using Unicam with Mydata. In Unicam I have a Theta Offset setting for each package witch determines the default rotational angle with respect to the pin 1 setting within the package data. With Mydata, the package inform

I've gone round and round on this very subject with our manufacturing engineer. He prefers to use panel fiducials and I prefer board fids. I've seen the result in placement from bowed PCB's in the machine. Skewing the board a fraction will throw off

We used to run GSM's on our SMT lines but now have new machines. I have all old programs from GSM's zipped and archived on our server. We have new orders for a handful builds that ran on GSM. I might be able to import those old files into our off-
