It's unusual to use a horseshoe shaped pad for a 0805. Commonly when people want to reduce the paste volume to reduce solder balling, they print a "home plate" aperature. We print paste 1:1 with the pad. �IPC-7351 LP Wizard� is the library mainten

Frequency to verify the reflow profile

Electronics Forum | Fri Jun 03 10:15:14 EDT 2005 | PWH

We do both our ovens once a week. If something looks out of tolerance (we've developed acceptable tolderances based on many recorded profiles over time and oven mfg. specs.) we wait a couple hours and try again. The recorded data over time is very

After profiling with a scrap board of the product I'm profiling, I would immediately send the MOLE through with one thermocouple only, no board, to provide a standard that I could reproduce without depending on scrap boards. I used that setup before

QS and ISO can really play a part here. If so, the best way I found was to run parallel T-couple ports to the thermocouples of the oven. Now you can run a board and gather all your thermal information and set your temps. Now use parallel ports to

Rework units with parylene coating

Peter: Based on our company's experience with removing a variety of different coatings, including parylene, the BGA's can be removed. We would use a chemical etch followed by a neutralizing process. We would then reflow the devices and pry them off

SMT Stencil Aperatures
