ZIF Socket for SX48?

Direct Digital Labs

I've chosen the SX48 for the microcontroller·for many of our products that require a microcontroller and would like to know if there is a ZIF socket available for the 48P TQFP package in order to program the devices before they are placed on the board. On the prototypes I have a header to program the chips but for the final designs I’d like to stay away from this for EMI reasons.

Yes there is, but you will pay dearly for it: http://www.xeltek.com/pages.php?pageid=119#QFP48

Shouldn't be an issue if you are in production since it's cost will be ammortized over the entire production line using the chip.

Seems most of the programming adapters use the Enplas line of sockets: http://www.enplas.co.jp/english/business/espc/test_burnin/pdf/catalog013.pdf

be sure you aquire the right type, part FPQ-48-0.5-06 is an example of a suitable socket (also the most expensive since it is thier clamshell variety (ZIF), OTQ-48-0.5 (03 or 10 suffix) would also work but is not ZIF (1.7 kg max actuation force)


Thier american branch office is in Sunnyvale, CA, website is here: http://www.enplas-ets.com/

Another option is in circuit programming using clips like: http://www.emulation.com/catalog/off%2Dthe%2Dshelf%5Fsolutions/debugging%5Faccessories/wedgeclips/

Though thier price is just as expensive as the socket, though I found·Agilent E2614A 0.5 Wedge clips for $39 here: http://used-line.com/b2545p1pr2-Used-leads.htm

Which may be your best bet if it is a low quantity production.

Excellent! Cost should not be a problem since we should be doing runs over 1000 units.
Thanks for your help.
