A boring question but needed---
I find soldering a pair of wires to tiny microphone capsules to be a daunting task. I tried both lead and silver and while I am succeeding it is slow and I overheated a few capsules.
Short of cutting PCB boards to mount these does anyone know if there exists, a socket to receive the common lead spacings of small capsules?
Thanks
Fritz

Shouldn't be so tough. How are your soldering skills? Tools? Can you solder a transistor to a PCB quickly and effectively?
I've soldered enough stuff in the last 50 years that I set off the lead detectors in the lab. Reflow ovens, tiny irons, rework stations----- At any rate I'm old, the capsules are very tiny, and the leads don't take solder very well.
But your main comment-soldering a xsistor to a PCB--sure. I can make up a bunch of tiny boards to hold the capsules-I was just wondering if they made a socket for these. Probably it is the area of the periodic table marked "unobtainium".
thanks

Sorry. We get all types here, some can't solder.
If you have experience and confidence, I won't repeat the teachings of flux, cleanliness, pre-tinning. Of using a touch of lead solder to break-down no-lead stuff. And being my age, I can't say anything about stronger lenses and brighter lights.
Maybe the move from Panasonic to some Chinese production line has changed the product enough to matter. I had drawers-full when I quit work but that was quite old stock.

I use eutectic solder for the capsules (63/37). This has the lowest melting point and solidifies fastest to minimize cold solder joints. Of course a temperature controlled soldering iron is a must, along with my alligator clip parts holder.
Most of the capsules I get today come with pins for PC mounting.
I also use a a five diopter magnifier, and rest my hand on the bench to steady it. When doing small item soldering I don’t enjoy caffeine before, but have to wait until after. Works for me, but the smallest I go is SOIC size parts. I did once get some 0102 parts that were listed as 1020, just threw them out. (Not worth the postage to return them.)

Thanks for the further comments. I drew up a very complex (4 holes!) PCB board and will have a bunch made up. Meanwhile I can flux and solder a few mics "as is" for now to keep the project on schedule.

A company called Mill Max makes a wide range of machined sockets and pins. You can lay out a circuit board to hold them, and if you put them in the right place and use the right type of pin/receptacle, you now have a special purpose connector for anything you'd want. Digikey and Mouser carry a lot of their products, and here's a pointer to their catalog: Catalog | Mill-Max Mfg. Corp.
The basic process is to measure the pins you have and find a compatible contact type that will fit the pin. Then choose a model using that contact type that is in stock somewhere and also fits the PCB or mechanical assembly you want to use. For square or rectangular pins, use the diagonal dimension as the lead diameter.
