When faced with high mass, high cost, sensitive PCBs and now with the added challenges of Pb-Free Vapor Phase is the only safe reflow method for component and joint integrity. A-Tek is the National Distributor for Asscon Vapor phase reflow. Asscon

I have a PCBA job which has on the top side a few standard QFN components (0.4mm pitch) and a big module (35mmx60mm) with 1.13mm BGA pads: https://imgur.com/a/YUGgejW To be clear, this module is composed of a PCB with some components on top and some

Resources are: * IPC-7525A - Stencil Design Guidelines, 3.5.2 Step-Up Stencil This type stencil is useful when it is desirable to print thicker solder paste in a small portion of the stencil. An example would be a ceramic BGA where it is necessary t

Hi, I'm using WS-820 by Alpha metals and works good, but you must take in consideration the humidity and temperature that you have in your facility, In the process that we're following we left the board printed during 2 hrs and works ok (no pop up ef

Would like opinions on which brand of leaded water soluble solder has the longest print life. we're currently using Alpha WS-809. Each board goes through the printer every 15 minutes or so, and we wind up re-printing most boards as the solder isn't

I like AIM solder paste, personally. But, much like asking which pick and place machine is best on this board, you're likely to get as many opinions as there are paste manufacturers. I just took a look at Alpha's datasheet for this product, and it

I have a customer want to add an SMD coil to the board, which they used to hand soldering all the time. I want to know is there footprint/land pattern size that I should follow? Any recommendation?

I would go with wire thickness + 0.4 to 0.8 mm for pad width, and pre-tinned lenght + 0.5mm what seems to me like problem is that it can easily roll off the pads in reflow oven

We are looking for a good solder/desolder machine for state-of-the-art pcb rework. A step up from the Pace/OK Industries is the level I am researching. The application is a nice R&D Lab on state-of-the art PCBs. Anybody who has suggestions or recomme
