Does anyone know of a quick method for developing reflow profiles for a Conceptronics HVA 102 reflow oven? Our plant is exceptionally busy and it's difficult to get access to the machine. I've been told by a few folks the oven has enough zones (7)

Greg; The universal profile concept maybe misleading. the main objective of a reflow system is to reach a certain temperature and maintain it for the required period of time. If your initial profile is set to accomodate this on any board the only va

Thanks Dave. About your second comment, the issue is placing BGA connectors mirror image (male, and female), the connector sometimes shifts during placement before reflow. we are using a six mil stencil for both sides with minimum paste deposit. a

Two things: 1 A flat surface will probably help the "balls on the socket sliding off the ridge of HASL" problem, but possibly consider less risky choices for your flat surfaces that immersion silver, like: OSP, ENIG, and immersion tin. 2 Don�t throw-

I worked as a tech for a company that produced momagraphy equipment about 5 years ago. Every so often we had a problem with a board that was suspected to be the board material itself and used the mamography equipment to check this. In some cases it

is it easy to program ? e) User friendliness. Is the equipment easy to operate ? f) Tact Time. g) 2nd Hand Market Cost of the equipment. Rough guesstimate will do. I got feedback that noone service this machine anymore. Is it true? and that parts a

I'm constantly being flooded with information by sales reps on x-ray and other types of equipment to inspect BGAs. Most of these items are simply beyond our capital budget constraints. I've witnessed dozens of demos, and to be honest, I really don'

We experienced a random no contact at ATE on our board. The board I'm building consist of 9 BGAs, all of them are OK except for one, intermittently the tester will prompt no-contact message. It's happened on a diff. I/O, but only happened on that pa

What about conveyor speed? I tried to manage that the speed of the board and the speed of the wave were nearly the same at that point where the leads are leaving the wave. But actually I haven�t seen icycling except at one time and that was solved r

We're stencil printing a Loctite 3614 Chipbonder adhesive, and we're using BioAct SC-10 presaturated wipes to clean the stencil after printing, without much luck. Operators are not able to remove all adhesive material left in the aperatures, and aft
