PCB ni iki?
PCB bivuga icapiro ryumuzunguruko wacapwe, arirwo rutwara amashanyarazi yibikoresho bya elegitoronike nigice cyibanze cyibicuruzwa byose bya elegitoroniki.PCB izwi kandi nka PWB (Icapa ryacapwe).
Ni ubuhe bwoko bw'ibikoresho bya PCB bushobora gucibwa hakoreshejwe ibyuma bya laser?
Ubwoko bwibikoresho bya PCB bishobora gukatwa nicyuma gikonjesha cya laser kirimo icyapa cyumuzunguruko cyanditswemo icyuma, icyapa cyandikirwa kumpapuro zumuzunguruko, epoxy ikirahure fibre cyacapishijwe imbaho zumuzunguruko, ikomatanya ryimyandikire yumuzunguruko, imbaho zidasanzwe zacapwe zumuzunguruko nizindi substrate. ibikoresho.
Impapuro PCB
Ubu bwoko bwimyandikire yumuzunguruko bukozwe mubipapuro bya fibre nkibikoresho bishimangira, bigashyirwa mumuti wa resin (fenolike resin, epoxy resin) hanyuma ukuma, hanyuma ugashyirwa hamwe na kole yometse kuri electrolytike y'umuringa, hanyuma ugakanda munsi yubushyuhe bwinshi n'umuvuduko mwinshi. .Ukurikije amahame y'Abanyamerika ASTM / NEMA, ubwoko nyamukuru ni FR-1, FR-2, FR-3 (hejuru yavuzwe ni flame retardant XPC, XXXPC (ibyavuzwe haruguru ni retardant retardant). Bikunze gukoreshwa kandi binini- umusaruro mwinshi ni FR-1 na XPC byanditseho imizunguruko.
Fiberglass PCBs
Ubu bwoko bwimyandikire yumuzunguruko ikoresha epoxy cyangwa yahinduwe na epoxy resin nkibikoresho fatizo bifata, hamwe nigitambaro cya fibre fibre nkibikoresho bishimangira.Nubu ni ikibaho kinini cyacapwe cyumuzunguruko kwisi hamwe nubwoko bukoreshwa cyane bwumuzingo wacapwe.Mubipimo bya ASTM / NEMA, hari uburyo bune bwimyenda ya epoxy fiberglass: G10 (non-flame retardant), FR-4 (flame retardant).G11 (gumana imbaraga zubushyuhe, ntabwo ari flame retardant), FR-5 (gumana imbaraga zubushyuhe, retardant flame).Mubyukuri, ibicuruzwa bidasubira inyuma bigenda bigabanuka uko umwaka utashye, kandi FR-4 ibarwa kuri benshi.
Gukomatanya PCB
Ubu bwoko bwicapiro ryumuzunguruko rishingiye ku gukoresha ibikoresho bitandukanye byongera imbaraga kugirango bibe ibikoresho fatizo nibikoresho shingiro.Umuringa wambaye umuringa wa laminate ukoreshwa cyane cyane ni CEM ikurikirana, muribo CEM-1 na CEM-3 aribo bahagarariye cyane.Umwenda fatizo wa CEM-1 ni umwenda wibirahure, ibikoresho byibanze ni impapuro, resin ni epoxy, flame retardant.Umwenda fatizo wa CEM-3 ni umwenda wibirahure, ibikoresho byibanze ni impapuro za fibre fibre, resin ni epoxy, flame retardant.Ibiranga shingiro byibanze byacapwe byumuzunguruko uhwanye na FR-4, ariko ikiguzi ni gito, kandi imikorere yimashini iruta FR-4.
PCBs
Ibyuma byubatswe (umusingi wa aluminium, umusingi wumuringa, icyuma cyuma cyangwa Invar ibyuma) birashobora gukorwa muburyo bumwe, bubiri, ibyuma byinshi byacapishijwe imbaho zicapye cyangwa icyuma cyumuzingi cyacapishijwe imbaho ukurikije imiterere yabyo nikoreshwa.
PCB ikoreshwa iki?
PCB. Porogaramu.Mubisabwa bifite umutekano muke, PCBs igomba kuba yujuje ubuziranenge bwo hejuru, bityo rero tugomba gufatana uburemere buri kintu cyose cyibikorwa bya PCB.
Nigute gukata laser ikora kuri PCBs?
Mbere ya byose, gukata PCB hamwe na laser bitandukanye no gukata hamwe nimashini nko gusya cyangwa kashe.Gukata lazeri ntabwo bizasiga umukungugu kuri PCB, ntabwo rero bizagira ingaruka kumikoreshereze ya nyuma, kandi guhangayikishwa nubukanishi hamwe nubushyuhe bwumuriro bwatangijwe na lazeri mubice ntibisanzwe, kandi inzira yo gutema iritonda.
Byongeye kandi, tekinoroji ya laser irashobora kuzuza ibisabwa byisuku.Abantu barashobora kubyara PCB bafite isuku ihanitse kandi yujuje ubuziranenge binyuze muri tekinoroji yo gukata laser ya STYLECNC kugirango bavure ibikoresho fatizo nta karubone kandi ibara.Byongeye kandi, kugirango hirindwe kunanirwa mugikorwa cyo guca, STYLECNC yakoze kandi ibishushanyo bifitanye isano nibicuruzwa byayo kugirango birinde.Kubwibyo, abakoresha barashobora kubona umusaruro mwinshi cyane mubikorwa.
Mubyukuri, gusa muguhindura ibipimo, umuntu arashobora gukoresha igikoresho kimwe cyo gukata lazeri mugutunganya ibikoresho bitandukanye, nkibisabwa bisanzwe (nka FR4 cyangwa ceramika), ibyuma byubatswe (IMS) hamwe na sisitemu-mubipaki (SIP).Ihinduka rituma PCBs ikoreshwa mubihe bitandukanye, nka sisitemu yo gukonjesha cyangwa gushyushya moteri, ibyuma bya chassis.
Mu gishushanyo cya PCB, nta mbogamizi ziri kumurongo, radiyo, ikirango cyangwa izindi ngingo.Binyuze mu kuzenguruka kuzuye, PCB irashobora gushyirwa kumeza, bikanoza cyane imikorere yimikoreshereze yumwanya.Gukata PCB hamwe na laser bizigama ibikoresho birenga 30% ugereranije nubuhanga bwo gukata imashini.Ibi ntabwo bifasha gusa kugabanya ikiguzi cyo gukora PCBs yihariye, ariko kandi ifasha kubaka ibidukikije byangiza ibidukikije.
Sisitemu yo gukata laser ya STYLECNC irashobora guhuzwa byoroshye na sisitemu isanzwe ikora (MES).Sisitemu yateye imbere ya sisitemu ituma ibikorwa bigenda neza, mugihe ibintu byikora bya sisitemu nabyo byoroshya imikorere.Turabikesha imbaraga zisumba izindi zahujwe na laser, imashini ya laser uyumunsi iragereranywa rwose na sisitemu ya mashini mubijyanye no kugabanya umuvuduko.
Byongeye kandi, ibiciro byo gukora bya sisitemu ya laser biri hasi kuko nta bice byambara nko gusya imitwe.Igiciro cyibisimburwa nibisubizo byavuyemo birashobora kwirindwa.
Ni ubuhe bwoko bwo gukata laser bukoreshwa mugukora PCB?
Hariho ubwoko butatu busanzwe bwa PCB laser ikata kwisi.Urashobora guhitamo neza ukurikije ubucuruzi bwawe bwo guhimba PCB.
