@AspirationH hey guys, your server is down as well as your clients.

The problem of running LMIC stack on your beloved ATmega328P is the limited flash program memory. The ATmega4808 gives that extra flash and RAM to fit the entire stack while leaving plenty for your application code.

During chipageddon, you can't be choosy. Whatever packaging your supplier gives you, you take it and run!

@lukebayes @GregDavill Same experience with this connector. Just wouldn't reflow properly.

@GregDavill There's that cursed 2 row USB C connector! That hidden 2nd row was my nightmare for two years, shorts, failed joints and bent legs. Never again!

Matte black soldermask. QFN, 0402 passives, and USB-C connector. 🤩

@FedExHelp Do we still need to print out the commercial invoice when the soft copy has been uploaded? Called @FedEx Malaysia and they insist on still printing the invoices out. @DHLexpress doesn't need hard copy once soft copies of invoice has been uploaded. Confuse...

Best feeling after completing a P&P job is cutting off these waste tapes. 😍

@osterwood It doesn't have a model or manufacturer but got it from Alibaba: alibaba.com/product-detail…

@rocketscream Very nice. What MFG / model? Where did you get it?

First time playing with the tape splicing tool! It's so satisfying and addictive. I could do this all night even though I have no real reels to splice. That's a boatload of $7 Digi-Reel and MouseReel saved from now onwards!

@tdarlic It does use the metal connector too. The yellow color adhesive tape is an add-on to hold the cover tape together. I got them from Alibaba: alibaba.com/product-detail…

@rocketscream I'm also interested which model is this. I use a different model that needs to be fed each time with metal connector. This might be a better solution

@jonoxer Got it made on Taobao for just $200 shipped on slow boat to Malaysia.

@rocketscream That's so beautiful!

Now that I've discovered Lachlan does stainless-steel fabrication for food production assembly lines, my imagination is going wild at fabricating stands for my Kayo A4 pick-and-place machines. It could be done with a full deck, or a skeleton version with disks for the Kayo feet.

Part 3 of the HWGC P&P guide is up: youtu.be/8NxJyYwczGo

@jaydcarlson @JLCPCB Using JLCPCB's minimum solder mask bridge of 0.1 mm, 0.4 mm QFN fits just nicely for the opening to be there. This holds true for their green solder mask, any other colour you had to forego that opening.

Bingo, but instead of numbers, you circle the pads that @JLCPCB decides to leave solder resist around.

0.4mm pitch QFN-48 mounted with our PnP machine! Glad that work awesomely!

@lukebayes You shouldn't be seeing too much of the capacitor and resistors in the reject bin. Those jelly beans parts usually works out of the box. Both pick & mount height plus the threshold is the 3 things that could make that bowl empty.

This is most of our waste (not counting ICs) from setting up and calibrating the pick and place for 20 units. I'm pretty sure we'll lose less as we get more experience, but it still hurts. Many of the resistors cost $0.005, but there are lots in there that cost much more.

@lukebayes Glad that it help your journey into the P&P world.

@rocketscream I couldn't shake how familiar the @rocketscream logo looked, and after sleeping on it, I realized that it was your great blog post that got me looking at the HG / SMT / Kayo machines. Thank you for that too! rocketscream.com/blog/2020/07/0…

Shout out to @rocketscream for some super helpful tips on my PnP YT videos. Thanks!

@MichaelGuntsche The ATmega version should be by end of this month while the SAMD21 version is unknown due to chip shortage and LoRaWAN module shortage.

@rocketscream Hi, do you have an update on when they will be available?

Big and little brother. More than a year tinkering on countless revision, perfecting them and ironing out design and manufacturing bugs. Prepping for production! #lorawan #arduino #microchip instagram.com/p/CR_OhEnhxe0/…

@SmallBatchA If you follow the datasheet's part orientation on the tape with the tape at 90 degree, it should be correct on most machine.

Most of the time the rotation information imported from customer CAD is not correct. We manually review and make corrections prior to running the job

Our very first video on YT! Many have asked us to make a tutorial on the HWGC pick and place machine, here you go: youtube.com/watch?v=D8Ai-Y…
