Ubuyobozi bwa PCB bufite igipande kimwe, ibice bibiri nuburyo bwinshi, muribwo nta karimbi kangana numubare wibice byinshi.Kugeza ubu, hari ibice birenga 100 bya PCB, kandi abantu benshi PCB ni ibice bine nibice bitandatu.None se kuki abantu bavuga bati: "kuki PCB igizwe n'abantu benshi cyane?"Ikibazo?Ndetse ibice bifite ibyiza byinshi kuruta ibice bidasanzwe.

1. Igiciro gito

Kubera urwego rumwe rwibitangazamakuru hamwe na file, igiciro cyibikoresho fatizo kubibaho bidasanzwe bya PCB biri munsi gato ugereranije nibibaho na PCB.Nyamara, igiciro cyo gutunganya ibintu bidasanzwe PCB irarenze cyane ugereranije niyindi-PCB. Igiciro cyo gutunganya urwego rwimbere ni kimwe, ariko imiterere ya foil / core bigaragara ko yongerera igiciro cyo gutunganya urwego rwo hanze.
Odd-layer PCB ikeneye kongeramo uburyo butemewe bwa laminated core ihuza uburyo hashingiwe kubikorwa byububiko bwa kirimbuzi. Ugereranije n’imiterere ya kirimbuzi, umusaruro w’uruganda ufite ifu ya fayili hanze yububiko bwa kirimbuzi uzagabanuka. Intangiriro yinyuma isaba gutunganyirizwa hamwe mbere yo kumurika, byongera ibyago byo gushushanya namakosa ya etch kurwego rwo hanze.

2. Kuringaniza imiterere kugirango wirinde kunama
Impamvu nziza yo gushushanya PCBS idafite numero idasanzwe ifite ni uko inomero zidafite numero zoroshye kugorama.Iyo PCB ikonje nyuma yuburyo bwo guhuza imirongo myinshi, impagarara zinyuranye zimurika hagati yimiterere yibanze hamwe nuburyo bufatika bizatera PCB kunama. Mugihe ubunini bwikibaho bwiyongera, ibyago byo kugonda PCB igizwe nuburyo bubiri butandukanye byiyongera.Urufunguzo rwo gukuraho ikibaho cyumuzunguruko ni ugukoresha urwego ruringaniye.Nubwo urwego runaka rwo kugonda PCB rwujuje ibyangombwa bisabwa, nyuma yo gutunganya neza bizagabanuka, bivamo kwiyongera kw'igiciro.Kuko inteko isaba ibikoresho byihariye nibikorwa, ibice byo gushyira ibice biragabanuka, bityo bizangiza ubwiza.

Hindura byoroshye kubyumva: mugikorwa cya tekinoroji ya PCB, ibice bine byubuyobozi biruta kugenzura ibice bitatu, cyane cyane mubijyanye no guhuza ibice, urwego rwintambara rwibice bine rushobora kugenzurwa munsi ya 0.7% (IPC600) ubunini bwibibaho bitatu, impamyabumenyi yintambara izarenga ibisanzwe, ibi bizagira ingaruka kuri SMT no kwizerwa kwibicuruzwa byose, bityo rero uwashushanyije rusange, ntabwo ari umubare udasanzwe wibishushanyo mbonera, nubwo byaba ari imikorere idasanzwe, bizaba yagenewe guhimbira igipande kimwe, 5 gishushanya ibice 6, igorofa 7 8 ikibaho.

Kubwimpamvu zavuzwe haruguru, abantu benshi ba PCB barateguwe nkibice, kandi ibice bidasanzwe ni bike.
