Screaming Circuits: Supply-chain

PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

30-second Philosophy - Wait or Rev Part 2

When you sell a house, the offer they make sounds great until you realize that the big number gets a lot smaller after accounting for replacing the roof, digging out the 60-year-old heating oil tank and fixing the 80-year-old plumbing.... Read more

Quoting PCB Assembly got you down?

In five years, plenty of new chip fabs will be online and we'll be able to buy those microcontrollers again. Of course, the brand new AugInt drive chips will still be hard to come by, but what breakthrough new technology... Read more

Supply Chain Woes - An open letter to microcontroller companies

To all of you out there who design, manufacture and sell microcontrollers - I'm talking to you! Actually, I'm talking to anyone who makes chips that have programmable configuration bits and overlapping model numbers. What do I mean by "overlapping... Read more

Why are we here, revisited

In December, 2018, I wrote the first "Why are we here?" post in this series. December, 2018 was about one year before we, in the electronics manufacturing business, started hearing about the impact of the Covid-19 pandemic on distant suppliers.... Read more

Pinouts, Package Changes and Subs

With so many components on allocation, having extended lead times or simply not available, minor re-design is the popular task of the day. MCUs can often be replaced with another family member and most passives and power components have options... Read more

Scam alert in the components world

As if there aren't enough challenges for all of us right now, we have been receiving reports of scammers impersonating legitimate component suppliers. They claim to have hard to get parts available, but just take your money and give nothing... Read more

Tip of the Day: Again with the Standard Not Standard

Sometimes the standards-steering-you-wrong aren't just in house, but come from Industry. Case in point the three-terminal linear regulator. Back when TO-220 packaged semiconductors were first hand chipped out of boiling lava, the LM7805 three-terminal voltage regulator established an informal standard... Read more

I'm sure you are getting tired of us telling you that. We're certainly tired of saying it, but it is still the world we live in. It may not let up until the middle of next year. So, here it... Read more
