In my experience Through Hole equipment normally racks up the downtime due to the amount of process variables. For SMT you would normally try to capture your workhorse machines Utilization. For example a chipshooter inline with glue dispenser,screen

Are we now talking about some "Vintage Collection" cars or the regular ones that do not have much re-sale value? In the former case, it would surely be worth spending on maintenance. However in case of SMT line equipments, one should consider 7-10 y

Greetings all, I did some measuring and found out that, thick golden line connects metal cases around RS232 pins (plaese check the new picture I added) to only undermost row of 32 rows of DIN41612. Btw, the connection port on the right is DIN41612 w

Hello everyone, I have a question regarding wavesoldering and measuring if a proces/machine is in control. I made a custom carrier for measuring contact time, parallelism, solder temperature, coveyorspeed and some data of the preheat section. The s

Hi Russ, Thanks for the input. The squeeze out we are reworking is very very thin since it has been flattened so it is actually easier to remove than usual but I agree, with a pad this small it could exert a bit of stress on the bond line if rework

Mike: An omega meter has very little to do with ion chromatography. * IPC TM-650, 2.3.25B, Detection and Measurement of Ionizable Surface Contaminants is a process control method that washes boards with an isopropanol / water solution and measures

Hi Processman, I would say that 92% is realistic if you have low mix - high volume manufacturing. In this case, the only reason for the machines to stop is to: - change reel (on ASM machines you can splice them together, so theoretically with ASM

measuring Paste volume or at least paste height is an essencial part of any SMT process. You've got to control those input's.... Paste volume determines how much solder is available for your joint so theres a direct to joint reliability / PCB reliabi

Maybe throw in some paste measurement equipment?
