App note: Processing instructions for mounting of through-hole LEDs

Do and don’ts when mounting through-holes LEDs, app note from Vishay. Link here (PDF) Through-hole LED cases usually consist of epoxy casting compounds with duroplastic properties. It is in the nature of things that optical semiconductor devices require transparent materials with the best possible optical features. Unlike standard IC mold compounds, which use reinforcing fillers […]

App note: Through-Hole versus SMD components

App note from Vishay on the advantages of using Through-Hole mounting. Link here (PDF) Most electronic gadgets are designed to interface with humans, and we humans are very abusive to most electronic devices. We drop them, poke them, open and close them, and in general feed stuff into and out of them. It is well […]

NEW PROTOTYPE: USB Infrared Toy through-hole PCB

We took the next-gen USB IR Toy v1.1 circuit and rearranged it into a through-hole PCB. It’s the basic Infrared Toy with a couple additions: Raw infrared signal detector for frequency measurement Breakout area with all the unused pins, tap in and do something interesting Check out the design, and get a PCB for $7.

Free PCB Sunday: through-hole Infrared Toy

We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. An all through-hole version of […]
