I had cracking caps from the ICT and a variation in the length of the probes (due to wear and tear) that press down the PCB. That put lots of mechanical stress on the PCB. So have also a close look at the ICT, or another other test fixtures you use.

After a detailed check the cracking was most likely from the ICT and a variation in the length of the probes (due to wear and tear) that press down the PCB. I am very certain that was the reason.

We use both Panasonic and JOT. JOTs are a good conveyor. The Panasonics will probably cost you less. Check the used equipment market. That's where we got all of ours and I haven't had any issues with any of them except the normal where and tear o

Are you using specific tooling for each part, or just generic? If so it could be pushing down at an angle and slightly tearing the PCB. We use the same style press as you but make custom fixtures to fit each connector and hold each PCB tight.

hello Zac, if you are running pump at 100% and there is not enough wave then you will probably need to empty solder bath and clean everything. also check pump parts for tear and wear. eached solder inlet can make a lot of problems when it comes to w

Hi Rob, We encountered it on a 6x6mm device, hence, we could consider it as fine pitch. I suppose that it may also have something to do with improvements in the speed of the feeders. Honestly, we don't have that visibility bec our customers do not

Hi Liza, several years ago we had problem like that only with Carrier Tape made by Ploycarbonate material and by using High Speed pick & place. Very few pbms met by using low speed P&P machine. Problems have been solved by using Polystirene Carri

Stefan - We are using an automatic sealing equipment and have several controls also. The particular machines used for processing these products could be narrowed down to 5 machines at most. The sealing temp, pressure and dwell time are checked on a
