Can anyone please share a document which details about the soldering defects if you have less or the excessive preheat time, soak time, peak temperature, time above liquidous (TAL)and cooling time. Appreciate your help in advance.

There is a lot of Asian manufacturer who can answer your question, I'm sure it won't take long to be heard .... ;)

I have to agree with Dave here. Can you compare the datasheet pad recommendations to your design ? It may help to show the forum a picture of the bare PCB pad design along with a pic of the bottom terminations on the part. What Stencil thickness a

Is TS-2414 insulating varnish material suitable for conformal coating of PCBAs? How can its performance be tested? What properties should be looked for on its data specs to conduct initial assessment if it is a suitable coating material?

We have a Rehm oven that can vibrate hard enough to shift parts on the board. The vibration is due to flux build up on the exhaust blower. If we don't clean it regularly we start to see parts shifting in the oven.

Can you possibly elaborate on your problem and why you think you have an unidentifiable vibration?

Hi Steve, thanks. please suggest me any supplier who can provide us accelerometer for reflow oven. Regards, Ameen

The melting of the solder during reflow itself can center up or skew a component. This could be pad size differential, incorrect pad size, unequal solder deposition amounts, pad spacing in reference to component size just to name a few.

I can't answer your question as it's been way too long since I did any Quad IVc work, but at some point bobpan will probably reply and give you exactly what you need.
