Ball Grid Array (BGA). A surface mount technology leadless package with the connectors to the board placed in an array on the bottom of the package. They are attached to the board with tiny balls of solder placed on each contact. Pin Grid Array (P

Hello everyone, I am currently running a gold plated SMT board and am experiencing tiny solder balls between the pads and the masking between the 20 mil pitch devices. I'm looking at these boards with a 60x microscope. IPC-610 say's any visible solde

Hi, What size via's are you guys seeing, as the ones in our products are incredibly tiny, and via's are very small now days. The via's on the boards we have are dramatically smaller than the pad on an 0402. Grant

Wow, they claim 1000 cycles of -65 to 150. I wonder if this was done with the 24mm part. With those tiny joints underneath, they must have exactly matched CTE's with their test boards.

@Stephen How big was the adapter board? It's challenging to depanelize and tedious to manually put these tiny assemblies in a tray.

On big chips, we use a tape printing device, I think it is a Brother PT1750. We have a small device, though, that is in an SO8 package, and the only thing we've come up with is to scratch a product letter code and the program date with a stylus. Th

If the Bliss carts would help you can cut some money out by buying aluminum bakers carts at your local restaurant supply house for less than $100/each and then buy ESD trays from another local source (Bliss is rather pricy). You will have to hang a c

I wouldn't mix it in a jar with new paste. But in another jar to be used on the next job, sure. I mean if your concern is contaminates, doesn't that mean its contaminated on the stencil? Unless the board is a hard one to print, or has really tiny

We still build a legacy product with a primitive backplane using silver plated fork terminals for outside world connections. After some 20 years of no problems the fork terminals on raw stock PCBs were black and almost unsolderable. Because of the

Since the inductor is electro-magnetic, that means the device is composite of coil and ferrite metal. The inductor inside the reflow oven meets with blower motors which close to the inductor and generate magnetic field. With such conditions, Lawren
