| What oven temperature should be used to reflow solder (Sn63Pb37) on a PC board (0.075" to 0.100" thickness) in 5 to 10 minutes? Profiling - tedious but important. As said, start with the paste manufacturers recomendation which is usually publishe

| We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized water

| | Has anyone had any experience or data using vibration during the reflow process. | | We introduced a vibration device attached to the fixed rail on a Vitronics reflow oven. The reason was to prevent skewing on large PLCC devices. The process work

| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

| Love the picture. | | We are considering the PRC 1500. It combines a thermoflo unit with a MBT 250A which we currently use. Does anyone know the difference between the TF200 and the TF700? This is the first I have seen the TF700 mentioned. | |

| Greetings, | | Can anyone tell me what temperatures pcb's should have when coming out of a forced convection reflow oven and out of a wavesoldering machine. | Also, is there any danger of the pcb's giving off some kind of gas or vapour which can b
