if use tray cannot solve the problem, you can change from the design 1）Reduce the effect of temperature on PCB 2) PCB USE HIGH TG 3) BOARD THICKNESS TOO THIN 4) MODIFY THE BOARD SIZE 5) Reduce the V-CUT depth.

I've never lost memory in a BGA from heat removal. However we can create a profile on our BGA rework stations to remove using bottom heat only. This exposes the BGA body to temperatures of around 190 to 200C. I have a colleague that has a machine

One of the major problems with snap off's is heat from the wave weakens the joints. Try using more holes but smaller size. V-grooves may also be an option, but depth control is a problem as most are not NC machine controlled. Direction through the wa

We'd repair a drop board like this. Here's what our old friend Jeff Ferry said is a published article ... When boards lose their edge: when the corner of a circuit board breaks or is damaged, the problem cannot be ignored by Jeff Ferry One of the m

Hi Mark, Couterbore is possible in two way's during PCB Manufacturing. Couterbore plated and non-plated. Meaning that the entire hole will either have to be Plated or Non-Plated. Prefered Methode is Plated, to accomplish this your PCB house would

Yes, doing the DoEs on your wave to achieve optimum settings that deliver the best results on your worst board is correct method. If not clear on the process, there are still wave solder process classes out there you can attend or hire in-house. If y

If there is a way to ensure that the product is reliable, it is to ensure the predictability of its PCB, which is an important part of the product. In fact, PCB is the core component in almost all electronic products (from phones to computer systems)

From the poor bonding strength of the board, the surface quality problems of the board are divided into: 1. The cleanliness of the board surface; 2. The problem of micro graphite (or surface energy) on the surface. PCB circuit board proofing Youke bo
