Countersunk holes on PCB

[dino]

Hi all,

I'm making an enclosure cover from FR4 with black soldermask, and it would be great if I could mount it using countersunk screws.

Does anybody know a PCB manufacturer that can make a PCB with ~2.6mm countersunk holes? (for M2.3 screws)
Preferably in Shenzhen.

Poshalji mi gerber/dxf.
Ja proizvodim shtampu u prototipnoj izradnji.

Proces proizvodnje se zasniva na mehanichkoj obradi bakra.
Zenkvane rupe nisu problem.

Eurocircuits can do this.

Some manufacturers can do in Shenzhen!

Hvala na ponudi, treba mi veca kolicina, ENIG + mat crn soldermask, i osetljiv sam na cenu, pretpostavljam da ti to nije interesantno.

So far I found PCBWay in Shenzhen, if you insert countersunk holes, price is raised by more than two times at >100pcs.
My guess is that Eurocircuits is similar.

Pozlatu ne radimo.

Nudimo samo srebro.
Razlog je kojekakva opasna i zakonom regulisana hemija koja se koristi u prpizvodnji pozlate.

Svi smo osetljivi na cenu i mi koji pokushavamo da se hvatamo u koshtac sa kineskim cenama znamo koliko shta koshta.

A ti ako hocesh poshalji informaciju i mi cemo ti odgovoriti sa ponudom.

Mogu da t ikazhem da imash relativno dobrog proizvodjacha  EIPCB u Nishu a isto tako i jednu manju radionicu to negde u Novom Sadu cini mi se.

Ako je tvoj zahtev relativno jednostavan i u pitanju je samo oblik i vrsta rupe to nebi trebalo da predstavlja neki narochit problem u proizvodnji,

Manufacturing seeks places with cheap labor cost and weak currency.

Soon enough China will price itself out of the game  and some other country ( Vietnam for example ) will be the new what ever.

If the cost increase is too great from the board shop, you could extend out the solder mask a little more & countersink the 2 holes yourself on the drill press. Once you set the drill press stop, it would take you less than 20 seconds tops. A black screw head would be nice

I don't think that price increase would scale as much, however Eurocircuits is many times more expensive to begin with.
