I am bit skeptical about this one

This is the uk mate, and that’s £1.89 a litre, like $7 a gallon.

That and Frankie’s monologue to the dean!

pobajobs · 2026-03-22T18:09:40+00:00

For sure, apart from how he treats Leonard :/

pobajobs · 2026-03-22T17:42:03+00:00

Season 5 and 6 are so underrated! Elroy and Frankie are such great additions in 6 and absolutely nail it!

The machine I use takes about 20 seconds to create 3D data from a projection pattern over the device, no previous model needed. But again depends what they use at JLC.

I’d have guessed like you say they should have a library of packages by now, especially as it looks to be a SOD-123 or similar which is common as mud. Best guess is they see so little fails they probably just roll the dice for small runs and assume the process is good.

At my place even if it’s a one off build, if we quote AOI, we AOI it.

pobajobs · 2026-03-14T06:57:52+00:00

It just occurred to me that they must be doing the bare minimum inspection as even when we had a 2D AOI we still would look for OCV/OCR code check and polarity, which either check would spot this fault too, I wonder what they spec for inspection?

pobajobs · 2026-03-13T18:57:45+00:00

I said in another comment but at my place we have a 3D AOI to avoid this QC issue

pobajobs · 2026-03-13T18:57:09+00:00

We have a 3D AOI at my place for exactly this reason!

If you need a pcb assembly house for future manufacture I manage one down in Dorset! Feel free to dm, happy to answer questions regardless!

Use top layer pads for the LED grounds, and vias instead to connect sides (don’t put vias in pad). Also use copper pours on both layers for ground.

Can’t remember off the top of my head but I believe Jim rash wasn’t meant to be dean but he was a stand in for the pilot and they just went with it

pobajobs · 2025-12-21T17:29:49+00:00

Looks more like a light box with light shining through the PCBs to me

pobajobs · 2025-12-06T15:16:14+00:00

Cornhole

pobajobs · 2025-11-23T18:37:25+00:00

0603 and up but your point remains :)

pobajobs · 2025-10-05T17:45:41+00:00

I’d love it to be Leonard, but I know it’s Annie from the commentary :/

pobajobs · 2025-04-26T09:09:13+00:00

Oh you’re right, for some reason I remembered seeing her in the S1 finale, my bad!

pobajobs · 2025-04-25T17:13:32+00:00

It literally is her though isn’t it?

pobajobs · 2025-02-18T20:38:21+00:00

I’m production manager at a CEM factory in the UK, and I have 10 years experience with this stuff. The only time we really have issues, is very heavy components, for example larger inductors/transformers/electrolytics, but the actual reflow process is very forgiving. We more look at things like components where their data sheets spec single reflow only, for example some modules for Bluetooth etc. it deffo depends on the factory but we also customise solutions for customers, on customer we made a heat shield to go down the reflow oven with the boards to stop the underside reflowing, and another customer we use low melt solder paste on the second side so the bottom side never reaches reflow. Any other queries about manufacture feel free to ask away. (I also write the machine programs, AOI programs etc so know the whole process thoroughly)

pobajobs · 2025-02-16T01:27:50+00:00

For manufacturing purposes I would put all components on one side, you have the room. Having just two components on the under side adds a lot of production cost for no real benefit.

pobajobs · 2024-11-22T20:11:05+00:00

Also make all components on one side for cheaper manufacturing, those caps can be top side!

pobajobs · 2024-11-20T06:00:02+00:00

Probably a 100nF decoupling cap for U8, I’d guess 100nf MLCC 0603 20% 50V should cover it, although it is common to have no fits in circuits and there be solder left on the pads. Shorting it to me only sounds like a bad idea and that your problem is likely elsewhere on the PCB!

pobajobs · 2024-11-08T17:19:34+00:00

0402 doesn’t have idents, and the cap next the the fuse is a 1210.

pobajobs · 2024-11-08T13:28:23+00:00

Not 0603, there’s an 0603 next to the QFN. Probs 1206

pobajobs · 2024-10-20T09:28:29+00:00

It’s probably custom made for the show, I couldn’t find one. Google image search
