PCB
Ronovar,
Koji kinezi su ti to napisali. JLCPCB je definitivno najjeftiniji bilo koja dimenzija PCBa, druga je stvar što neke "dodatne usluge" naplaćuju.

Što se tiče DIY izrade, ja jako malo naručujem od kineza već sigurno više od 95% radim sam i već sam preko 15 godina u tom "poslu". Prošao sam razne faze od gotovih fotoslojenih pločica do farbanja kaširanog vitroplasta sa fotolakom i sada sam na foto-foliji. Da napraviš jedan PCB bilo koje veličine potrošiš hrpu vremena. Za fotopostupak sa foto-filmom trebaš poštivati točno što piše u uputama za određeni film, u prijevodu od nanašanja filma na vitroplast do nagrizanja treba proći oko 2h vremena i sa time vodovi ispadnu bome profi. Brži postupak je naravno sa peglom ali koliko znam dosta ovisi kakav se ima printer,papir tako da rezultat može da bude svakakav. I to je bez solder maske i silkscreena, što misliš koliko vremena treba da na pojedini PCB staviš još ta dva sloja.
Ovo sve što govorim se podrazumijeva da se PCBi rade onako tu i tamo za DIYere,možda kakva mala serija ako imaš sreće za nekog malog obrtnika i sl.

Ima i ona opcija sa nekim printerom pa da direktno na PCB naneseš lak/boju/što već na mjesta na kojima bakar treba da ostane, onda nagrizanje i nakon toga opet printanje solder maske i silk screena to bi moglo biti dosta brzo. Bušenje je po meni priča za sebe i ne znam točno što bi sve trebalo poduzeti da se na CNCu izbuše rupe a da ti ne pobjegnu pa makar i za par desetih od mjesta na koje je predviđeno da ide rupa.

I sada dolazimo do možda najvažnije činjenice u svemu tome. Koliko to naplatiti. Ako imaš stalni posao i ne trebaš neku pretjeranu dodatnu zaradu onda si recimo to tako ograničen samo "vremenski" da u ono slobodno vrijeme koje imaš preko vikenda ili par sati nakon posla da napraviš nekome PCB pa naplatiš materijal+nešto sitno.

Evo za sebe mogu reći da je moja cijena izrade PCBa 0,38kn/cm^2(jednostrani, 1,6mm vitroplast, 35u bakar). Dobije se PCB sa rupama,vodovi pokositreni, ali bez silk screena i solder maske,mogu se potruditi na napravim i dvostruki PCB ali naravno bez metaliziranih rupa. Da li ja radio 5x5cm ili 20x20cm PCB, 1kom ili 10kom vremenski mi je skoro isto jer nanašanje foto-folije,osvjetljivanje,razvijanje,nagrizanje, pa sve do fercinanja bakra i bušenja rupa prođe relativno brzo nebitno koliko imam PCBa. Još tu treba dodati vrijeme rezanja, vitroplasta, pranje bakra da bude čist ko suza jer u protivnom folija/lak/što već se neće dobro prihvatiti i prođe ti 3-4h samo tako, a zamisli koliko bi još vremena prošlo da trebaš staviti silk screen i solder masku.
Koliko bi ti naplatio to što si potrošio pola radnog vremena na možda par komada 5x5cm PCBa. Kinez te ošiša po cijeni i izgledu PCBa dok si rekao keks, osim naravno imaš toliko posla da možeš otvoriti firmu i štancaš dnevno tko zna koliko PCBa pa si onda kupiš profi opremu za izradu, ali i onda porezi,cijene materijala i ostalo ti određuje kolika bi ti bila prodajna cijena a to je sigurno skuplje od kineza.
