PCB Etching DIY hamwe na CO2 Laser

Igishushanyo cyihariye kuva Laser Etching PCB

Nkibintu byingenzi byingenzi mubice bya elegitoroniki, PCB (icapiro ryumuzunguruko wacapwe) yo gushushanya no guhimba ni impungenge zikomeye kubakora ibikoresho bya elegitoroniki. Urashobora kuba umenyereye tekinoroji ya pcb yo gucapa nkuburyo bwo kohereza toner ndetse ukanabimenyereza wenyine. Hano ndashaka gusangira nawe ubundi buryo bwo gutobora pcb hamwe na CO2 laser ikata, nkwemerera guhinduranya byoroshye pcbs ukurikije ibishushanyo ukunda.

Igishushanyo cyoroshye cya pcb cyubatswe murwego rwo gukingira hamwe nuburyo bubiri bw'umuringa (nanone bita umuringa). Mubisanzwe FR-4 (ikirahuri kiboheye na epoxy) nibikoresho bisanzwe byo gukora nka insulation, hagati aho hashingiwe kubisabwa bitandukanye kumikorere yihariye, ibishushanyo mbonera, hamwe nubunini bwibibaho, dielectrics nka FR-2 (impapuro za fenolike), CEM-3 (ibirahuri bidoda na epoxy) nabyo birashobora kwakirwa. Umuringa ufata inshingano zo gutanga ibimenyetso byamashanyarazi kugirango wubake ihuriro hagati yinyuma hifashishijwe ibice byabigenewe hifashishijwe ibicuruzwa cyangwa ibicuruzwa bigurishwa. Kubwibyo, intego nyamukuru yo gutobora pcb nugukora imirongo yumuzingi hamwe numuringa kimwe no gukuraho umuringa udafite akamaro cyangwa kubatandukanya.

Kugira akajisho gato kuri ihame rya pcb, turareba uburyo busanzwe bwo guterana. Hariho uburyo bubiri butandukanye bwo gukora bushingiye ku ihame rimwe ryo gushira umuringa wambaye.

- Ibisubizo bya PCB

Imwe ni iy'ibitekerezo bitaziguye aribyo gukuraho ahasigaye umuringa udafite akamaro usibye inzira zumuzunguruko. Mubisanzwe, twemeje igisubizo nka feri chloride kugirango tugere kubikorwa. Bitewe nibice binini bigomba gushyirwaho, hagomba gufatwa igihe kinini kimwe no kwihangana gukomeye.

Ubundi buryo ni ubuhanga cyane kugirango ushire umurongo uciwe (vuga neza - urutonde rw'imiterere y'umuzunguruko), biganisha ku gutwarwa neza kwizunguruka mu gihe utandukanya icyuma cy'umuringa kidafite akamaro. Muriyi miterere, umuringa muke urashishwa kandi umwanya muto urakoreshwa. Hasi nzibanda kuburyo bwa kabiri kugirango nsobanure uburyo bwo gukora pcb ukurikije dosiye.

Nigute ushobora gukora pcb

Ni ibihe bintu bigomba gutegurwa:

ikibaho cyumuzunguruko (ikibaho cyumuringa), gusiga irangi (matte yumukara), dosiye yububiko bwa pcb, gukata laser, igisubizo cya ferric chloride (gutobora umuringa), guhanagura inzoga (gusukura), igisubizo cyo gukaraba acetone (gushonga irangi), sandpaper ( gusya ikibaho cy'umuringa)

Intambwe zo Gukora:

1. Koresha dosiye yububiko bwa PCB kuri dosiye ya vector (kontour yo hanze irashobora kuba laser etched) hanyuma uyishyire muri sisitemu ya laser.

.

3. Fata ikibaho cyumuzunguruko muri pliers hanyuma utange irangi ritoya kuriyo

4. Shira ikibaho cy'umuringa kumeza yakazi hanyuma utangire lazeri ishushanya irangi

5. Nyuma yo gutobora, ohanagura ibisigazwa by'irangi ukoresheje inzoga

6. Shyira muri PCB etchant solution (ferric chloride) kugirango ushire umuringa wagaragaye

7. Gukemura irangi rya spray hamwe na acetone yo gukaraba (cyangwa kuvanaho irangi nka Xylene cyangwa gusiga irangi). Koga cyangwa uhanagure irangi ryirabura risigaye kurubaho birashoboka.

8. Gutobora umwobo

9. Kugurisha ibikoresho bya elegitoronike unyuze mu mwobo

10. Byarangiye

Kuki uhitamo laser etching pcb

Twabibutsa ko, imashini ya laser ya CO2 itera irangi rya spray hejuru ukurikije ibimenyetso byumuzunguruko aho kuba umuringa. Nuburyo bwubwenge bwo gutobora umuringa wagaragaye hamwe nuduce duto kandi ushobora gukorerwa murugo. Nanone, amashanyarazi make ya laser yamashanyarazi arashobora kuyikora abikesheje gukuraho byoroshye irangi rya spray. Kuboneka byoroshye kubikoresho no gukora byoroshye imashini ya laser ya CO2 ituma uburyo bukundwa kandi bworoshye, bityo urashobora gukora pcb murugo, kumara umwanya muto. Byongeye kandi, prototyping yihuse irashobora kugerwaho na CO2 laser yanditseho pcb, bigatuma ibishushanyo bya pcbs bitandukanye bihinduka kandi bigahita bigaragara. Usibye guhinduka kwishusho ya pcb, hari ikintu cyingenzi cyerekana impamvu uhitamo co2 laser ikata neza neza hamwe na laser nziza nziza itanga umurongo uhuza imirongo.

Imashini ya CO2 laser pcb ikwiranye nibimenyetso byerekana ibimenyetso, ibyiciro bibiri nibice byinshi bya pcbs. Urashobora kuyikoresha kugirango ushushanye igishushanyo cya pcb murugo, kandi ugashyira imashini ya laser ya CO2 mubikorwa bya pcbs bifatika. Gusubiramo cyane no guhuzagurika neza nibyiza cyane nibyiza byo gushushanya laser no gushushanya laser, byemeza ubwiza bwa PCBs. Ibisobanuro birambuye kugirango ubonelaser engraver 100.

Inzira imwe ya PCB ikora na UV laser, fibre laser

Ikirenzeho, niba ushaka kumenya gutunganya byihuse kandi nuburyo buke bwo gukora pcbs, UV laser, icyatsi kibisi na fibre laser imashini bishobora guhitamo neza. Lazeri itomora umuringa kugirango usige inzira zumuzunguruko bitanga ubworoherane mubikorwa byinganda.

Series Urukurikirane rwibintu bizakomeza kuvugururwa, urashobora kubona byinshi kubyerekeranye no gukata UV laser hamwe na laser etching kuri pcbs mubutaha.

Kurasa mu buryo butaziguye imeri niba ushaka igisubizo cya laser kuri pcb
