Mugushushanya amakariso ya PCB muri Igishushanyo mbonera cya PCB , birakenewe gushushanya byimazeyo ukurikije ibisabwa nibipimo.Kuberako muri SMT itunganya patch, igishushanyo cya PCB ni ngombwa cyane.Igishushanyo cya padi kizagira ingaruka ku buryo butaziguye kugurishwa, gutuza no guhererekanya ubushyuhe bwibigize.Bifitanye isano nubwiza bwo gutunganya patch.Noneho ni ubuhe buryo bwa PCB bwo gushushanya? 1. Gushushanya ibipimo byubunini nubunini bwa PCB: 1. Hamagara isomero risanzwe rya PCB. 2. Uruhande ntarengwa rwa padi ntiruri munsi ya 0.25mm, kandi diameter ntarengwa ya padi yose ntabwo irenze inshuro 3 ibice bigize aperture. 3. Gerageza kwemeza ko intera iri hagati yimpande zombi zirenze 0.4mm. 4. Amapaki afite aperture arenga 1,2mm cyangwa diametero ya padi irenga 3.0mm agomba kuba yarakozwe nka pome ya diyama cyangwa ipima ya quincunx. 5. Kubireba insinga zuzuye, birasabwa gukoresha plaque ya oval na oblong.Uburebure bwa diameter cyangwa ubugari ntarengwa bwa panne imwe ni 1,6mm;intege-zumuzunguruko zumuzingi wibice byimpande zombi zikeneye kongeramo 0.5mm kuri diameter.Kinini cyane padi irashobora gutera byoroshye gusudira bitari ngombwa.
PCB ikoresheje ubunini busanzwe:
Umwobo w'imbere wa padi muri rusange ntabwo uri munsi ya 0,6mm, kuko umwobo muto uri munsi ya 0,6mm ntabwo byoroshye gutunganya mugihe cyo gukubita urupfu.Mubisanzwe, diameter ya pin yicyuma hiyongereyeho 0.2mm ikoreshwa nkumurambararo wimbere wa padi, nka diameter ya pin yicyuma cya rezistor Iyo ari 0.5mm, umwobo wimbere wa padi uhwanye na 0.7mm , na diameter ya padi biterwa na diameter y'imbere.
Bitatu, ingingo yo kwizerwa yibikoresho bya PCB:
1. Symmetry, kugirango habeho kuringaniza uburemere bwubuso bwumugurisha ushongeshejwe, amakariso kumpande zombi agomba kuba ahuje.
Umwanya wa padi.Umwanya munini cyane cyangwa muto padi bizatera kugurisha inenge.Noneho rero, menya neza ko intera iri hagati yibice birangira cyangwa pin na padi birakwiye.
3. Ingano isigaye ya padi, ingano isigaye yibigize impera cyangwa pin hamwe na padi nyuma yo guhuzagurika bigomba kwemeza ko umugurisha ashobora gukora menisk.
4. Ubugari bwa padi bugomba kuba busa nubugari bwibice bigize pin cyangwa pin.
Gukosora igishushanyo cya PCB, niba hari akantu gato ka skew mugihe cyo gutunganya ibishishwa, birashobora gukosorwa bitewe nubushyuhe bwo hejuru bwumucuruzi ushongeshejwe mugihe cyo kugurisha.Niba igishushanyo cya PCB kitari cyo, kabone niyo imyanya yo kuyishyira ari iyukuri, inenge yo kugurisha nkibice bigize offset hamwe nikiraro cyo guhagarika bizagaragara byoroshye nyuma yo kugurisha.Kubwibyo, mugihe utegura PCB, igishushanyo cya PCB kigomba kwitonda cyane.
Uburebure bwa 1,6mm icyatsi kibisi cyagurishijwe urutoki rwa zahabu PCB ikibaho FR4 CCL ikibaho cyumuzunguruko
