The QFP pitch is 0.5mm. Pad size is 1.475 x 0.3mm, and the new aperture size is 1.32 x 0.22mm. I'm not sure about whether or not it is lasered, but on the newly ordered stencil I selected the polishing option. Looks like the pad width is already 2/3

Leaded HASL on small pads can be quite difficult to print on...the HASL tends to be domed rather than flat..and that can affect print quality...you really need a perfectly flat pcb pad to print paste on when you are assembling 0.5mm QFPs. If the pcb

It will be tough to get a good line for that cost. You might want to start by looking at Mydata and Juki for the machines. Ekra for the screen printer and Heller for the oven is where you might want to start. If you have not already you might want

I have two machines - Emerald-X and Topaz-X. I cleaned (and changed Koganei electromagnets) only in Topaz-X - Emerald-X is in very good condition :) But my Emerald-X have SF (not FNC) heads. If head 1 is OK - change the relays with head 2 and check.

For closure to all readers of this thread...many thanks to Michal for this support. Trans-tec (USA) was great in replying to our countless emails on this topic. We sourced a replacement solenoid # A041E1-48W for our Emerald-X = YV88X. The part was a

Welcome to SMT! I highly recommend exploring the process of adding unique reel identifiers to your reels and tracking locations, or even kitting, using these barcodes. You may also see this referred to as serializing or license plating. Implementin
