Can be solder through it.
What is the purpose of a solder mask that can be soldered through.

I thought a solder mask was there to prevent soldering beyond the intended pad area.

Could you make some of these? Universal PSU, Capacitor and Diode Combination Board (Pre-scored and easy to snap into sections) - PCBs There's several forum members who are after them but they're not available from the store and little indication of when they will be available again...

Yes ! Andrew , in fact you have right soldermask is to prevent......but in fact is not a "real soldermask " .......it's something like a glossy flux ( dried ) which prevent oxides of copper traces and in the same time you can solder through pads ( help soldering ) ..............and of course you must be careful to solder only on the pad's places.

All the best.

Ordered five Fr4 tinned boards from Mihai and received them today.
They look really professional and I'm very happy with the result!

He finished them during weekend a couple of days after payment and shipping was really fast too!

I just wanted to write a good review here so you may feel confident about ordering from him. Communication via email was great, and it was a pleasure to deal with him.

Do you have plated through holes?
How well do the traces survive removal of component lead and re-soldering?

I will not make through plate holes , because inquiry is under 1% !

The traces on FR4 ( better than CEM , XPC , if required many re-solderings) , are strong enough.

Re-soldering is helped if traces are tined from beginning.

Re-soldering " traces- pad's life" it depends of soldering skills ( soldering time , de-soldering time) , soldering temperature , de-soldering temperature.

If you want, we can talk more to : msdesignerpro@gmail.com

I can answer you much faster through above e-mail.

All the best,

Mihai
