Please help us understand your situation better. * How do �Having Problems W/ Parts Moving At Reflow� and �When the boards come out of the oven the pads look very wet from flux� relate to one another? * Tell us about solder, flux, reflow profile, and

We are running a CV 400 Wave solder. We are having difficulty getting sufficient flux on the boards. It uses a reciprocating spray fluxer that is controlled based on time by a board sensor located on the load side conveyor. The problem is that there

Blow holes/ pin holes in solder joints are the result of multiple root causes. Suggested analysis might look like this; 1) What method of solder preservation is used on the bare board. (hasl,enig, osp, etc.) HASL can leave unwanted flux residues,

I have one of these before our oven, and there is no way to control the speed of the belts. Checking their website produces nothing. We have the unit open, but nothing inside appears to be adjustable. Anyone know where I can find a manual for this? P

Does anyone have any experience with a MyData Tray Wagon Magazine (TWM)? If so what do you do behind it for a conveyer? We received a TWM to test and it will not work with our conveyor system. MyData said to change to a different set of adjusting hol

I think your solder mask is a partial cause of your solder balling. Additionally, adjusting some machine set-up parameters may also help. 1 If we were talking about a single assembly problem, we�d be thinking about the laminate, but since you say t

Which type? * Solder beads (mid-chip solder balls, attached to the waste line of your chip caps and resistors) This is more paste volume related. * Solder balls that tend to be more randomly scattered (as in spattered)? This tends to be more profile

Dreamsniper, The optimum contact (dwell) time in the wave should be 2 seconds. Contact band width is a function of conveyor speed. For an example, 5cm of contact band width at 150cm/min. conveyor speed will give you 2 seconds of contact time and 2cm

Its no my turn to give some advise. My first question would be can you put the boards into a carrier of some sort. There are many wonderful companies that make carriers that are ment for running down a smt line. This can be expensive unless you order
