I saw a similar problem a couple years ago. In our case the issue was the original manufacture of the devices. The high temp spheres were misaligned from the beginning, and subjecting these parts to SMT reflow made the problem worse, and created is

Interesting Hege, however we xray 100% of these parts during our assembled PCB test process so I have to think this would have been caught seeing as this is not confined to one batch/year/upper level assy (same BGA, slightly different PCBs). That be

We check the resistors to value check them. We are using resistors that are not marked in any way shape or form. We also hand build everything so it is very possible to have our operators place the wrong part in the wrong spot. From a time point of v

There is no defined method that I am aware of. If your bulbs are old replace them. Other than that adjust the gain and offset until there is clear definition on the edges of the components. Keep an eye on the dump box.If the dump box stays relatively

We will look at the oven speed. We considered stiffeners but opted against that due to the risk of moving parts pre-reflow due to handling. 90 deg? I don't know. This may or may not help with the bowing. Considering there is little to no substra

Wondering how good the software is for the Quad QSA 30 is. Is it a pain to program? We have panels with 100 boards... 1500 parts, I hope you don't have to manually teach the whole panelized board. Any other info you can provide is welcome. We

Check the software version before you buy it. If it is not version 6.75 do not buy it. This is the last version released for this machine and fixes many bugs that made running a panelized board a nightmare. 0603 parts and above is where i would stay
