| if anyone has used or has one of these bga rework stations please give me your opinion on them. I am planning on using the sytem for not only rework but also low volume prototype production for hand built 1 or 2 qty pcb's, so ease of use is impor

| We currently bake plastic SMT parts in accordance with the IPC guidelines for moisture sensitive parts. Because we have double-sided boards that are subjected to either an aqueous or semi-aqueous cleaning process, we do a 24 hour bake at 125 deg.

We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inordi

If I brief shifting, I checked the component before it enter the reflow oven and saw that the IC is perfectly aligned on the pads but when it comes out from the oven the IC is floated on the pads. The floating is irregular and the IC is shifted away

what about tube (could be transparent) with opening at the bottom to pick up by operator and loading new fresh jars from top (vertical tower of solder jars). Each time when operator takes jar next one appears on the bottom etc.

Hi Aurther, Thanks for a prompt reply. I agree but unfortunately our AOI is 2D and misses a lot of solder defects especially on connector terminals which are surface mount. We are also dependent on operator at AOI to mark the defect if caught by AOI
