Fancy making your next board hotswappable? It's pretty easy, just install some Mill Max sockets into your standard PCB. It's been a while since I ran the previous GBs (
R1,
R2) and since I need some more sockets myself for my Lubrigante/Acrylic Gasket 60% thingy, it's time for another round. (
Reddit thread for reference.)
This GB is
Europe only as it doesn't make much sense importing the sockets and then sending them back to NA. (If you really really want some sockets though and live elsewhere, PM me.)

Join here: https://forms.gle/eft1GPyKHgVrfwMF6- Postage & packing: 4 GBP to anywhere in Europe (not just EU) for any number of sockets
- No MOQ on individual orders. We just need to reach 2500 total order quantity on each socket type to get the lowest price on each of the sockets. If there is risk of not meeting MOQ on some socket type I'll contact you with options (switch to the other type, go with the higher cost)
- Price includes 21% VAT and 5% PayPal fees
- Payment by PayPal in GBP, or by Revolut with a 5% discount and in any currency
- The GB will run till Sunday 13 October 2019
- I will send out invoices shortly after the GB closes. Unpaid invoices will be cancelled after 24 hours and order placed with Mouser
- Shipping from Mouser should take about 5 working days
- Once I receive the sockets I will pack them and send them out to you within 2-3 of days
PicturesSoldering the Holtite sockets: see
Soldering the Mill Max socketsIt's not difficult, just fiddly. You need to be careful not to get solder inside the sockets (requiring replacement). This is how I do it:
- Stand the PCB upright on one of the (usually longer) side
- Insert a batch of sockets into the PCB
- Set the iron pretty high (I use 400°C, the maximum the TS-80 allows)
- Heat the sockets up from the top (i.e. from the side the switch is inserted)
- Apply a small amount of solder from the other side around the protruding part of the socket. I use 0.5 mm solder but thinner would be even better
Any questions please don't hesitate to ask!UPDATE: All orders have been shipped and the GB is now complete. Thanks everybody for joining and for your patience!
