cum realizeazi o schema electrica

Recommended Posts

Posted

salut, am facut rost de niste scheme electrice private (ideei inovative), problema e ca acum trebuie sa le pun in practica, am terminat scoala acum multi ani la electronica (eram passionat de programare pe vremea aia), da imi mai aduc aminte putine lucruri despre corodat.

Exista cumva vreun dispozitiv cu care as putea realiza placutele electrice tip industrial, la un pret decet ? ma intereseaza doar schema pentru inceput.

Un simplu search pe google: Cheapest PCB makers, low volume | element14 .

Aici,jos, din slovenia

Hi Jonas,

If you can afford to wait few weeks for your PCBs, you might consider using an interesting PCB production service from Slovenia, offered by a local magazine named "Svet Elektronike" (PCB parcele). Their business model is to combine our orders (gerber files) and when a panel is populated, it goes into production. According to my experiances, this cycle takes up to 3 weeks.

So, if you prefer good price (specially when your PCBs are smaller in size) over delivery time, this is an option to be considered. Their price is 0.462 EUR/cm2 for single sided and 0.759 EUR/cm2 for double sided PCB, with green masks and white top silk. This is the price for 5pcs, VAT is included.

For example, 5 single-side boards with dimensions 3x4cm will cost you just 5.54 EUR + P&P.

Unfortunately, the page listed above is in Slovenian language, but this language is supported by Google translator. Additionally, I believe that people from the magazine can answer you if something is not clear.

Nevertheless, also feel free to contact me, if needed.

Best wishes, Ivan.

ce fel de placaj vei folosi simplu pe o singura parte, dubluplacat sau multistrat? ar trebui sa transpui schemele in Proteus si de acolo sa iti alegi tipul cablajului. dupa ce ai proiectul pcb-ului salvat in proteus poti sa il trimiti la orice fabrica de componente sa iti faca cate placaje doresti.

Intrebarea ta e putin cam confuza. N-ai specificat daca vrei sa le produci tu placile de cablaj imprimat sau doar sa ti le faca cineva dupa proiectul tau. Daca doresti sa le produci tu e cam greu. Placile se produc in mai multe moduri. Modul substractiv, pe care il foloseste fiecare electronist acasa, prin corodare cu clorura ferica sau acid azotic(foarte coroziv deci lucrat cu FOARTE MARE ATENTIE), metalizare care nu se poate face decit in fabrici pentru ca se folosesc utilaje complexe si foarte scumpe(poate sa ajunga la milioane de dolari) sau se mai poate folosi metoda gravarii, metoda care poate fi folosita si acasa dar unealta este scumpa. Un Bunghard CCD2 ajunge la 12000(doisprezece mii) euro.
Cit despre programul cu care iti proiectezi placile de cablaj imprimat sint O GRAMADA. Free sau Paid. Ai de unde alege.
