As with any issue like this, your miileage may vary with suggestions....but, here are the items I would consider: 1. Clinch tightness. I believe IPC gives a recommendation on the amount of bend in a clinched lead; make sure you're not beyond that.

Hi Dave, I think Lee's talking about PTH BGA Sockets not BGA devices. I worked with him for a long time and he's placed a lot of BGAs. Kind regards, Rob.

Dear all: I wonder how to avoid cracking the BGA if I want to remove it from the PCB assembly, re-ball it and solder it again. I need an answer considering: 1- The assembly could have been exposed to the ambient humidity for a long time. 2- The as

Hi all, I mean after post adhesive oven curing (SMD at bottom side) prior to manual insert of PTH components (top side), what is the recommended storage time prior to wave soldering in order to avoid pin/blow holes and sunken joints issues (pcb asse

Hi Experts, Understand from my friends, PTH crystal can get damage easily when subject to vibration or heat..For example, if crystal drop from table to floor, its internal part already damage @ crack which cannot be seen by eye. Besides, they als

It's what the customer wants. remember the customer is always right and that IPC is only recommended guidelines the last time I looked. I also belive IPC shows examples of PTH parts being preped and lap soldered to SMT pads so common sense says what'

I thought Contact Length refered to the travel distance the board stays in contact with the solder. I measured it using a tempered glass plate that also showed me if I had an even footprint of contact with the wave. By this definition, conveyor spe

assuming Sn05Pb93.5Ag1.5 Without knowing what you are trying to solder, PTH or SMT, the time might not be that far off. Does that time include stripping, cleaning, plating the leads prior to soldering onto the board?... pre-tinning the board as well

Before this wave solder pallet salesman blather gets too far out-of-control, let�s stop for a minute. The three major approaches you have are: 1 SELECTIVE SOLDERING: Using: * Specialty wave soldering machine to solder specific areas of a board * P
