Is a fresh lot. This bga is old date code 2010. we had received this BGA 2021 and the baking process is done during receiving time. Production received with vacuum seal , its very hard to tell how the BGA handling and stuff and the BGA already EOL. I

This massage is for clarifications on storage and handling of Moisture sensitive parts: Does chip resistors,capacitors and inductors need vacuum packing during usage life? For repacking of FPDs to limit reuse, is it necessary to use vacuum seler or s

We have started using an RGB LED and today ran the first boards down our line. I noticed an immediate issue with placing these. I'm using a quad QSP-2. The part sticks to the nozzle. The nozzles are clean. I have adjusted machine handling so that vac

HELLO MIKE, THE PROBLEM WITH THE VIA BEING IN THE MIDDLE OF THE PAD CAN BE HANDLED. IF YOU ARE HAVING PROBLEMS WITH SOLDER FLOWING THROUGH AT REFLOW YOU MIGHT WANT TO CHECK YOUR VACUUM AT YOU SCREEN PRINTER. SOMETIMES THE VACUUM THAT HOLDS THE PCB

I just wanted to know if anyone stores their vacuum sealed bags on their sides instead of flat. We are trying to save room, but I dont want to create defects either. The ones we have are tightly vacuum sealed and would like to store on their sides

Hi, Use nitrile or latex gloves for handling your product from your pre-coating cleaning step onward. In my opinion, conformal coating should be isolated from the rest of the factory floor. I'm not saying you need a clean room or even a white room.

Hello Peterson, If the contact tails protruded enough on the underside of the PCB, then you could do a "reverse" press fit. I do not believe that to be the case with the VHDM. Placement equipment is out of my bailiwick but; Usually small SMT connec

...ahh....memory lane. 10 years ago I worked on a project for a customer who needed a low cost, high volume board for RFID tags for cows (yes, moo). These boards were 0.50 inch in diameter, 50 per panel, double sided SMT punch style fabs. 300,000 b

Hi Derek, just curious of one thing - are the vias within the BGA's the only vias covered or are all vias on the board covered. Just trying to figure out what is making this area different from the rest of the board. Regarding leaching, I do not be

Greetings, We are discussing what should and what should not be baked and vacuum packed. Should we just concentrate on the fine pitch packages and the bga's? What about those components which come on blister tape, should they get baked and re-packed
