or air-leveled films are used. Gold is best of course.
I had some boards made as carriers to enable to mount smt chips on to through hole for use on breadboard.
Many patterns each board which were chaap from china , (i have a board shear).
I had some which were ENIG which have also become difficiult after 2 years or so.
Gold would seem to be the best long term option but i do not know of any supplier who offers this at a reasosnable price(my usal supplier does not offer gold , only ENIG).
Best would be to buy a carrier for the chip i require online.
Do not know the relevant search terms to use though.
I can never find the right carrier for the chip i need.
Current requriement it is for TI 4 port USB chip. I realise that it is going to be useless on a breadboard but just need a carrier to plug in to a custom PCB.
Personally, I was wondering how the OP made the jump from talking about a Hardware Abstraction Layer to solder...
I do not understand.
I have some old boards which are no longer solderaable.
Immersion tin (commonly used on home-made boards) is much thinner and less durable - it stops being readily solderable within months, IME.
This is my experience also.
The boards i have i thought to be hot air levelled with solder, not sure though now.
