Can excessive reflow(longer dwell time) cause open joint?

A couple of other potential issues are moisture/reflow related issues. This can include internal delaminations inside the component, potentially breaking or lifting the wirebonds. It may also induce warpage where the corners of the BGA will curl up.

It would help to see pictures, but I suspect the parts are seeing excessive strain when snapped into or removed from the pallet.

To my knowledge, the 40C was established as the maximum "safe temperature" for all tape and reel packaging. The actual specs may vary somewhat for different types of reel, pocket-tape, cover-tape but you must be concerned with the cover tape adhesive

Hello KA, When producing in kind of PCB product you have to base much of your decision on cost effectiveness, time, and quality. In order to get the best of all three you have to decide which you want to be your top priority. By adding an epoxy to

If I understand what you're saying, you are reaching reflow temp's on the top side while soldering bottom side components. You might want to run a glass gauge plate over the wave and make sure your contact pattern isn't too large. If your PCB is in c

HiP most of the time goes back to the component package itself. If they are on the periphery of the part, it is a result excessive of expansion and contraction from the temperature. If it is in the middle, other contributors come in place.

Find out were the excess flux is coming from. See if it can be eliminated or reduced at the source. Lokely coming from something other than SMT assembly.

Adhesion of conformal coating to plastic components

We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not alwa

I have used the PC-2500 from V-TEK and have encountered no problems. It has a motorised reel handling system and can handle various tape pitches and reel sizes.It has an accuracy in excess of 99%.Check out their website below. Billc
