PCB Assembly Services - Screaming Circuits: Allocation



Screaming Circuits is seeing more and more components in short supply or on allocation these days. A while back, we took a survey of our customers and found that on average, an engineer would spend about 16 hours sourcing parts for a prototype design.

Schottky top My question is has that changed? There are a few chip companies with a lot of parts in short supply, but what I hear the most about is the passive components. If you've designed a very specific power or radio chip, for example, I can see how a twelve week lead time can be a very big issue. But if it's just a 47pf, 6volt cap, a resistor or diode, is it really that difficult to find a sub quickly?

How much of an issue is parts availability today - really? Is it something that has a lot of visibility and little impact? Or is it something where the visibility and the impact are both pretty big? How much of a hassle and time sink is it for you now?

Hi Duane,

I focus on low volume production so my perspective may be a little different, but I'm constantly battling a lack of prototyping components being available for specific IC chips (recently DVI/ETHERNET/USB/etc). Without prototype quantities being readily available its hard to knock out a new prototype or designs. Hasn't really been an issue for passive components (at least not yet).

Having to contact each manufacturer is a lot of effort and time. I would prefer to pick up low volumes from distributors Digi-Key/Mouser/Newark/NuHo/etc.
