Ibintu 10 biranga PCB,
1. 20μm umwobo urukuta rw'umuringa wa Ikibaho cyumuzunguruko ,
Inyungu: Kongera ubwizerwe, harimo kunoza z-axis yo kwaguka. Ingaruka zo kutabikora: guhanagura umwobo cyangwa gusohora, ibibazo byo guhuza amashanyarazi mugihe cyo guterana (gutandukanya ibice byimbere, gusenya inkuta zumwobo), cyangwa kunanirwa gushoboka mugihe cyimitwaro ikoreshwa mubyukuri.
2. Nta gusana gusudira cyangwa gusana inzitizi zifunguye Inyungu: Inzira nziza ituma kwizerwa n'umutekano, nta kubungabunga, nta ngaruka. Ingaruka zo kudakora ibi: Niba bisanwe nabi, uzakora uruziga rufunguye kurubaho.Nubwo byakosorwa 'neza', harikibazo cyo kunanirwa mubihe byumutwaro (vibrasiya, nibindi) bishobora kunanirwa mugukoresha nyabyo. 3. Koresha CCL izwi cyane CCL, Inyungu: Kunoza kwizerwa, kuramba no gukora bizwi. Ingaruka zo kudakora ibi: Gukoresha impapuro zujuje ubuziranenge bizagabanya cyane ubuzima bwibicuruzwa, kandi mugihe kimwe, imiterere mibi yimashini yurupapuro bivuze ko ikibaho kitazakora nkuko byari byitezwe mubihe byateranijwe, urugero: kwaguka cyane imitungo irashobora kuganisha kuri delamination, gufungura uruziga no gukemura ibibazo, kandi amashanyarazi afite intege nke bishobora kuvamo imikorere mibi. Ibikoresho by'uruganda rwa ABIS PCB byose biva mubyamamare bizwi cyane mubihugu ndetse no mumahanga, kandi byageze kumubano wigihe kirekire wubufatanye nabatanga ibicuruzwa kugirango ibicuruzwa bitangwe neza. 4. Koresha wino nziza Inyungu: Menya neza ubwiza bwicapiro ryumuzunguruko, kunoza ubudahemuka bwo kubyara amashusho, no kurinda uruziga. Ingaruka zo kutabikora: wino mbi irashobora gutera gufatana, kurwanya flux nibibazo bikomeye.Ibi bibazo byose birashobora gutuma mask yabagurisha yitandukana kurubaho hanyuma amaherezo bigatera kwangirika kwumuringa.Imiterere idahwitse irashobora gutera imiyoboro migufi kubera gukomeza amashanyarazi kubwimpanuka / arcing.
5. Kurenga isuku ibisabwa bya IPC Inyungu: Kunoza isuku ya PCB bitezimbere kwizerwa. Ingaruka zo kudakora ibi: Ibisigisigi ku kibaho, kwiyubaka kugurisha bishobora kwerekana ibyago kuri masike yabagurishije, ibisigisigi bya ionic bishobora gutera kwangirika kwabagurishijwe hamwe ningaruka zo kwanduza bishobora gutera ibibazo byokwizerwa (guhuza ibicuruzwa bibi / kunanirwa kw'amashanyarazi ), kandi Byanyuma byongera amahirwe yo gutsindwa nyabyo.
Umucuruzi ugurisha mask Aluminiumuzunguruko
6. Kugenzura byimazeyo ubuzima bwa serivisi ya buri kuvura hejuru Inyungu: Gukora, kwizerwa, no kugabanya ibyago byo kwinjira mubushuhe. Ingaruka zo kudakora ibi: Ibibazo byubusembwa bishobora kubaho bitewe nimpinduka za metallografiya hejuru yubuso bwibibaho bishaje, kandi kwinjira mubushuhe bishobora gutera delamination, ibice byimbere ninkuta zumwobo mugihe cyo guterana no / cyangwa gukoresha nyirizina Gutandukana (gufungura inzira), nibindi. Gufata hejuru yo gutera amabati hejuru yintangarugero, ubunini bwo gutera amabati ni μ 1.5μm, kandi ubuzima bwa serivisi ni burebure. 7. Umwobo wo mu rwego rwo hejuru Inyungu: Amacomeka meza yo mu ruganda rwa PCB azagabanya ibyago byo gutsindwa mugihe cyo guterana. Ingaruka zo kudakora ibi: Ibisigisigi bya chimique biva mubikorwa byo kwibiza zahabu birashobora kuguma mu mwobo udacometse neza, bigatera ibibazo nko kugurisha.Mubyongeyeho, hashobora no kuba amasaro y'amabati yihishe mu mwobo.Mugihe cyo guterana cyangwa gukoresha nyabyo, amasaro yamabati arashobora gusohoka agatera uruziga rugufi. 8. Kwihanganira CCL byujuje ibisabwa na IPC 4101 ClassB / L. Inyungu: Kugenzura cyane umubyimba wa dielectric igabanya gutandukana kubikorwa byamashanyarazi ateganijwe. Ingaruka zo kutabikora: Imashanyarazi ntishobora kuba yujuje ibyangombwa bisabwa, kandi ibice biva murwego rumwe birashobora gutandukana cyane mubisohoka / imikorere. 9. Igenzura cyane kwihanganira imiterere, imyobo nibindi bikoresho bya mashini Inyungu: Kwihanganirana gukurikiranwa neza bizamura ubuziranenge bwibicuruzwa - byujuje ubuziranenge, imiterere n'imikorere. Ingaruka zo kudakora ibi: Ibibazo mugihe cyo guterana, nko guhuza / gushyingiranwa (ibibazo byapine-imashini iboneka gusa iyo inteko irangiye).Mubyongeyeho, kwishyiriraho shingiro nabyo birashobora kuba ikibazo kubera kwiyongera kurwego rwo gutandukana.Ukurikije amahame yo kwizerwa yo hejuru, kwihanganira imyanya yumwobo ni munsi cyangwa bingana na 0.075mm, kwihanganira umwobo wa diameter ni PTH ± 0.075mm, naho kwihanganira imiterere ni ± 0.13mm. 10. Ubunini bwa mask yo kugurisha ni muremure bihagije Inyungu: Kunoza imitunganyirize yumuriro wamashanyarazi, kugabanya ibyago byo gukuramo cyangwa gutakaza gufatira hamwe, kongera imbaraga zo gukanika imashini - aho bibaye hose! Ingaruka zo kutabikora: Mask yoroheje yo kugurisha irashobora gutera gufatana, kurwanya flux hamwe nibibazo bikomeye.Ibi bibazo byose birashobora gutuma mask yabagurisha yitandukana kurubaho hanyuma amaherezo bigatera kwangirika kwumuringa.Imitungo idahwitse kubera masike yoroheje yagurishijwe, irashobora gutera imiyoboro migufi kubera gutwara impanuka / arcing.
Abandi, nyamuneka rfq, hano!
