06/10/2021, 4:03 PMThanks Matt. I am not sure I understood? you mean the socket or PCB?

06/10/2021, 4:24 PMI guess it's a socket?

06/10/2021, 4:25 PMI didn't have a bread board that could accommodate it since the spacing between sides isn't a multiple

06/10/2021, 4:30 PMoh I see! I was actually looking for something like this: https://www.digikey.com/en/products/detail/chip-quik-inc/PA0107SOCKET/5978211?utm_ad[…]NYKvCW_D0_mkM56PIOc_mKWxClgf9jhwVVyrh6quJ0-RsfOAaAvsfEALw_wcB
So it is easier to switch between the chips? I am really bad with stencils

06/10/2021, 5:03 PMYeah, I'm not sure how they used it. I was going to solder pins to it and just wire wrap/pin connectors, but it'd be nice to be able to put it on a breadboard.

06/10/2021, 5:34 PM@mehdi : The chip itself is a QFN and it is kind of difficult to get sockets for them. The best resource I've found is Ironwood Electronics. They are pricey but generally you need only one of them.

06/10/2021, 5:40 PM@Matthew Guthaus, @mehdi: Also, the SRAM test board pictured above is essentially useless because two pins need to switch voltage domains for the thing to work right, but they were all glommed together underneath the chip where it is impossible to make alterations to the board. The pictured board works if everything is run at 1.8V. I don't have any testing systems that will run at that voltage, though.

06/10/2021, 7:49 PMThanks for the clarification @Tim Edwards @Matthew Guthaus. So is there any gerber files or altium scheme/layout we could use. I am just avoiding to do this from scratch and save some cycles. I guess for the 5 chips I could just solder them manually.
