Olsem wanem blong mekem PCB blong yu wetem CNC mo CircuitMill

Wan smol gaed blong PCB milim, izolesen, drilling, mo katem bod.

Yu no nid blong yusum ol kemikol we oli doti o ol bigfala masin blong mekem wan printed circuit board. Wetem wan smol CNC mo CircuitMill, yu save tanem desin blong PCB blong yu i kam wan bod long wokshop blong yu.

Gaed ia i pas tru long wok: mekem desin i rere, mekem ol rod blong tul, milim ol trace blong kopa, drillim ol hol, mo katem bod.

Wokflo blong PCB: eksportem kopa, drill mo outline fael; mekem mo lukluk long ol rod blong tul; afta milim, drill mo katem bod.

1. CNC PCB milim i wanem?

CNC PCB milim i wan wei blong mekem samting we i tekemaot materyel. Masin i yusum wan smol tul blong tekemaot kopa we yu no wantem long bod we i kavremap wetem kopa.

I gat tri wok we oli impoten: izolesen routing, drilling, mo katem bod. Ol rod blong tul oli mas stret mo yu mas lukluk fastaem long olgeta bifo masin i ron.

Tri lukluk blong sem PCB: ol kanal blong izolesen, ol hol we drill i mekem, mo outline cut wetem wan tab blong holem bod.

2. Ol samting we yu nidim

Yu nidim wan desktop CNC we i strong, wan copper-clad PCB blank olsem FR-1 o FR-4, ol engraving bit, ol drill bit, wan end mill, wan komputa wetem KiCad o narafala PCB desin program, mo wan gudfala wei blong holem bod. Yusum proteksen blong ae mo dust extraction, speseli taem yu katem FR-4.

3. Mekem mo rere long PCB

Mekem desin long KiCad, mekem sua se ol trace oli joen, outline i ful, mo ol design-rule check oli pas. Eksportem ol copper Gerber fael, Excellon drill fael, mo outline fael. CircuitMill i save prosesem olgeta lokal long browser blong yu.

4. Setemap CNC masin

Holem bod i flat long bed. Setem work origin mo Z zero long surfes blong kopa. Sapos masin i sapotem probing, jekem contact, travel, mo clearance fastaem.

V-bit i mekem wan narrow izolesen gap taem cut i shallow mo wan bigfala gap taem cut i deep. Ol saes long pija oli blong eksampol nomo.

5. Milim, drill mo katem

Yusum wan sharp bit mo wan conservative depth blong tekemaot kopa nomo we i nid. Afta milim, jekem ol trace blong incomplete izolesen, ol burr, mo ol pad we oli kasem damej. Afta, drillim ol hol mo katem outline laswan. Livim ol holding tab blong bod i no muv bifo las pass i finis.

Ol gudfala tingting

Stat wetem ol bigfala clearance, holem PCB i flat, testem feed mo depth long wan scrap bod, mo oltaem jekem preview blong ol rod blong tul. CircuitMill i givim wan klia rod i stat long PCB layout i go kasem bod we i rere blong yusum.
