You described cleaning the spindles and filters, but did you clean the nozzles? Perhaps you got some paste on the nozzle. Also, did you perform the vacuum and blow off testing? Make sure your solenoids are working properly. Is it all 6 heads that

Hi, It's not on your list, but we use an SPI and an AOI from SAKI. Very simple software interface and the same structure on all machines. As soon as the library is set up, a program can be created in a maximum of 20 minutes. The program creation go

I agree with Jon, that using Gerber data is a pain in the butt, but that doesn't answer your question about what software to use. CircuitCAM, VALOR, UniCAM (now Tecnomatix), and GC Place are the more popular third party software packages that deal d

Hi, I believe you have classic gold imbrittlement here. With 80 microinches of gold you are way over the limit. You can try to reflow longer time and at a higher temperature. The gold does not melt into the solder joint. The gold dissolves into

Hi, We are currently soldering only connectors, so there is not that much to do. For the wave we currently use palettes as we solder PCI cards but don't want to wash. So the palette keeps the flux off the board. My reasons for looking at changing o

Hey I'm having an issue with a samsung 421f component placer. The machine is fine on the first 5 boards then on the 6th or so it just throws them wherever. The problem is the smallest flat components start sticking to the nozzle even after hitting th
