If you have to order boards for your own DIY, that will not cost more, you have to paid the shipping for your boards all ready.
I did the same with see post #438 LT4320 based active rectifier
More people who order PCB in China should do that..it's my humble opinion
Sorry, I was looking at the wrong place. Of course I know how to follow links.
The only version I'm interested in is that with through-hole parts, not SMDs.
Nobody answered my question about the "minimum" scope I would need to use for the snubbers. Any of the small DMM size ones sold on eBay or Aliexpress will do? Or any board I can connect to a laptop or PC?
Which are the minimum MHZ I would need?
Hicoco, I do not understand what you wrote. What cost you 2$ for 10 boards? You have Quasimodo pcbs left that cost $2 plus $2 for shipping to Brazil? Which schematic?
I am using Siglent SDS 1052, it's a 50Mhz digital scope, I think it is also an entry-level scope, Rigol also has very competitively priced too.
Aliexpress is a good source. Sometimes they got free shipping.
Tomorrow is their biggest sale event in Aliexpress, it's their 11thNov...AKA 11.11, a yearly sale event. You may find a good choice of scope there.
Now this is for 5 Boards....That was last April for 10 Boards

These 5 boards may be for $2, but they are with the lower quality HASL surface finish. It's cheap and low quality and not good for plated through-holes. See for example the following description. (PCB Surface Finishes Comparison: HASL, OSP, & ENIG)
Try selecting the industry standard ENIG finish and see that ENIG surface finish alone is $16 for 5 boards. With shipping to US at $5.24, the total ends up at $23.24. How many board does one need? Normally only one board is required, so either you have to spend time to sell the other boards factoring in $4.65 self cost per board, packaging, payment and shipping costs or just count 1 board for $23.24.
And the above boards are with the light 1oz copper based traces. If one tries to use 2oz copper, that adds another $16 for the total of $39.54 for 5 boards or $7.91 per board.
