Embedding Active and Passive Components in Organic PCBs for More Reliability and Miniaturization
06/20/2017 | Thomas Hofmann, HOFMANN LEITERPLATTEN GMBH
Closing the Gap Between Design and Fab
Author Ben Jordan writes, "I think that CAD tool vendors have done a fantastic job of making design easier and faster, but there is still a huge gap between what a PCB designer intends, thinks, and lays out in CAD and what a PCB fabricator needs to build and assemble the boards with reasonable yields. It's one (good) thing to support universal data transfer formats, but that's not an automatic fix-all, either."
Validate Your Model Data
Do you test and correlate simulation models, or do you just take someone else's word for it? Let's be honest--we all want fast, accurate simulation models. Testing is difficult, time-consuming, and a general pain in the neck. If we take a close look at most the models we use, we'll likely raise questions that take time to resolve--time that most of us don't have in our project schedules.
The Pros and Cons of PCB Surface Finishes
Hot air solder leveling (HASL) was once the tried and true method of deliver consistent assembly results. However, ever-increasing circuit complexity and component density has stretched the capabilities of even horizontal solder levelling systems to their limits.

With recent events highlighting the intrusions on freedom of the press and freedom of speech, how soon before we regain control of our government? What happened to the government needing subpoenas before infringing on freedoms? How soon before we teach our politicians and bureaucrats to respect and fear us, and to realize that they work for us?
The Impact of Soldermask Processing on ENIG/ENEPIG Deposit Quality
Process control of the different steps involved in soldermask applications is paramount to the success of the ENIG/ENEPIG deposit.
