RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

PCBONLINE Blog: What's Going on in Testing the PCB Assembly?

PCBONLINE Blog: What's Going on in Testing the Printed Circuit Board Assembly? - RF CafePCBONLINE, a one-stop custom PCB/PCBA manufacturer for prototypes, has posted a blog that answers the question, "What's going on in testing the printed circuit board assembly?" Unlike most PCB assemblers, the advanced PCB manufacturer PCBONLINE can process functional tests before delivery so that our clients don't have to test on their own. PCBA testing at PCBONLINE includes the Automated Optical Inspection (AOI) test during the assembly process, functional test, and thermal aging test after the assembly. During the AOI and functional test, if the PCBA is good, the computer screen will display OK. Otherwise, it will display NG (no good), and all test process data can be recorded. The aging test consists of powering on the PCBA to let it work for some time depending...

2020: The Year that Was...

Anatech Electronics December 2020 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his December newsletter that features his short op−ed entitled "2020: The Year that Was... ," in which Sam assess how he well did in predicting various key industry trends at the end of last year. You can read his piece to see how he scored, but I do want to note a specific point. One of Sam's predictions pertained to the availability of broadband service in rural areas. The Wuhan Flu epidemic that caused most schools to implement a remote classroom environment exposed how deficient the system still is, even though we thought the issue had been pretty much resolved (goodness knows we've spent enough tax money to address it). Also included in the newsletter are a few pertinent industry headlines. Stand by for Sam's end-of-year predictions for 2021...
