From my understanding these China OEM machines are for very specific production with low flexibility. i.e. Smaller board sizes.....machines just for memory modules. With those examples they will beable to reduce conveyor sizes, linear motor sizes whi

I have a customer with up to 8% scrap from one board supplier and 1% from another supplier for solder dewett and no wet over ENIG finish with mask defined pads. Initially I suspected mask residue on pads because of the no wets but I have come to find

Hi Dave, The paste applied to the board ends up on the tombstone. The pad has a thin covering of solder most of the time, this is why I think they call it a dewet. Occasionally the pad shows some areas of gold and very rarely are some pads not wet at

I have two basic questions: 1. We have a number of small convection ovens and want to modify some of these for baking out parts when needed. We have tried pumping nitrogen into these but I still run between 35 and 50 RH. Has anyone tried converting a

Hi Brandon. You should always try to optimize / "balance" your line in a way so the machine with the shortest time per placement is your bottleneck. The other machines in the line should then have a 10 - 20 sec sorter cycle time, to be able to cope

The "BEST" thsat they could do is what is in the manual. BUT we all know that no-one that I know of designs boards with only 0805 on .100" centers with one component. CP 3 should give you on average maybe 10k per hour. IP 2 I really don't know sin

I would take the following method to start Which defect is taking the most labor time to fix. which defect is causing a bottleneck to your production. Fix the one causing the bottleneck first as it will improve your plant output and profits Then
