UwitekaInzira ya PCBni birebire birebire byubuyobozi byashyizwe kumurongo woherejwe hamwe no gushyiramo amanota amanota mugihe cyo gutunganya SMT. Ubugari bwibikorwa byubusanzwe ni 5-8mm.

Muburyo bwo gushushanya PCB, kubera impamvu zimwe, intera iri hagati yuruhande rwibigize hamwe nuruhande rurerure rwa PCB iri munsi ya 5mm. Kugirango hamenyekane imikorere nubuziranenge bwibikorwa bya PCB, uwashushanyije agomba kongeramo inzira kuruhande rurerure rwa PCB

Ibitekerezo bya PCB edge

1. SMD cyangwa imashini yinjizwamo imashini ntishobora gutondekwa kuruhande rwubukorikori, kandi ibice bya SMD cyangwa imashini yinjizwamo imashini ntibishobora kwinjira mubukorikori n'umwanya wacyo wo hejuru.

2. Ikintu cyibikoresho byinjijwemo intoki ntigishobora kugwa mumwanya uri muri 3mm z'uburebure hejuru yimpande zo hejuru no hepfo, kandi ntishobora kugwa mumwanya uri muri 2mm z'uburebure hejuru yibumoso n'iburyo.

3. Ifarashi y'umuringa itwara impande zose zigomba kuba nini zishoboka. Imirongo iri munsi ya 0.4mm isaba gukingirwa gukomeye hamwe no kuvura-abrasion, kandi umurongo kuruhande nturi munsi ya 0.8mm.

4. Inzira yimikorere na PCB birashobora guhuzwa nu mwobo wa kashe cyangwa V-shusho. Mubisanzwe, V-shusho ikoreshwa.

5. Ntihakagombye kubaho udupapuro kandi unyuze mu mwobo kuruhande rwibikorwa.

6. Ikibaho kimwe gifite ubuso burenze mm 80 bisaba ko PCB ubwayo ifite impande zombi zisa, kandi nta bikoresho bifatika byinjira mumwanya wo hejuru no hepfo yibikorwa.

7. Ubugari bwibikorwa birashobora kwiyongera muburyo bukwiye.
