Mu rwego rwo koroshya umusaruro no gukora, umuyobozi wa PCBPCB, Jigsaw muri rusange agomba gushushanya ikimenyetso, V-groove, no gutunganya inkomoko.
Igishushanyo cya PCB
1.
2. Ubugari bwuzuye bwa PCB uburyo bwa pcb ni ≤260mm (umurongo wa siemens) cyangwa ≤300mm (umurongo wa Fuji); Niba gluing yikora isabwa, ubugari bwuzuye bwa pcb uburyo bwa pcb ni 125mm × 180mm.
3. Igishushanyo mbonera cyuburyo bwa PCB hafi ya kare bishoboka, kandi birasabwa cyane gukoresha 2 × 2, 3 × 3, ... nuburyo bwo gucumbika; Ariko ntabwo ari ngombwa kuvuga ikibaho cyiza kandi kibi;
PCBV-GUCA
1. Nyuma yo gufungura V-gukata, ubunini busigaye X igomba kuba (1/1 1/3) Icyapa ubunini l, ariko ubunini buke x bugomba kuba ≥0.4mm. Ibibujijwe birahari ku bibaho hamwe n'imitwaro iremereye, kandi imipaka yo hepfo iraboneka ku kibaho gifite imitwaro yoroshye.
2. Kumuva ku gikomere kuruhande rwibumoso n'iburyo bwa v-gukata bigomba kuba bitarenze mm 0; Kubera imipaka ntarengwa ifatika, uburyo bwa V-CLATING uburyo budakwiriye Inama yubunini butarenze 1.3mm.
Mark Point
1. Mugihe ushyiraho ingingo isanzwe yo gutoranya, muri rusange usiba ahantu hatuwe udahujwe no kurwanya 1.5 Mm nini kuruta peripheri yingingo.
2. Ikoreshwa mugufasha optics elegitoroniki yimashini yo gushyiramo smt kugirango umenye neza ku mfuruka yo hejuru yinama ya PCB hamwe nibice bya Chip. Hano hari byibuze ingingo ebyiri zipiganwa. Ingingo zo gupima kugirango imyanya nyayo ya PCB yose muri rusange mugice kimwe. Umwanya ugereranije wimfuruka yo hejuru ya PCB; Ingingo zo gupima kugirango uhaze neza PCB optics ya elegitoroniki ya elegitoroniki muri rusange iri hejuru ya pcb pcb pcb pcb pcb Croint Crointy.
3. Kubice bya QFP (kare kare) hamwe na wire spacing ≤0.5 mm na bm ya ball array ≤0.8 Mm
Gutunganya Ikoranabuhanga
1. Umupaka uhuza ikadiri n'inama nkuru y'imbere, node iri hagati y'Inama nkuru n'inama nkuru itagomba kuba nini cyangwa ikaba yarenze, n'inkombe y'ibikoresho bya elegitoronike hamwe n'inama y'umuzunguruko bigomba gusiga MM irenze 0.5 z'umwanya wo mu nzu. Kugirango habeho imikorere isanzwe ya CNC yaciwe.
Ibyobo byukuri
1. Ikoreshwa muburyo busobanutse bwinama yumuzunguruko wose wa PCB Mubihe bisanzwe, QFP ifite intera iri munsi ya 0.65mm igomba gushyirwaho hejuru yacyo; Ibimenyetso bigaragara neza byinama yubuyobozi bwa PCB mugomba gukoreshwa muri babiri kandi bigashyirwa hejuru yimpande zo hejuru yibintu byanditse neza.
2. Umwanya uhagaze neza cyangwa umwobo uhagaze neza ugomba kubikwa kubice binini bya elegitoroniki, nka I / o Jack, Jathone, Jaggles, Marphone Jack, motos, nibindi
Umushinga mwiza wa PCB ugomba kuzirikana ibintu byo gukora no gukora mugihe utezimbere gahunda yo gushushanya puzzle kugirango umusaruro woroshye wo gutanga umusaruro no gutunganya, kunoza umusaruro, no kugabanya ibiciro byibicuruzwa.
