Codsiga

Lakabka Sare PCB (Lakabka Sare PCB) waa PCB (Printed circuit Board, looxa wareegyada daabacan) oo leh in ka badan 8 lakab.Sababo la xiriira faa'iidooyinka ay guddiga wareegga multi-lakabka, cufnaanta wareegga sare waxaa lagu gaari karaa in raad yar, awood design wareegga adag oo dheeraad ah, sidaas darteed waxa ay aad ugu habboon habsocodka signalka dhijitaalka ah-xawaaraha sare, mikrowave soo noqnoqda, modem,-dhamaadka sare. server , kaydinta xogta iyo goobaha kale.Looxyada wareegga heer-sare waxaa badanaa laga sameeyaa loox-TG FR4 ama qalab kale oo wax-qabad sare leh, kaas oo ilaalin kara xasilloonida wareegga heerkulka sare, qoyaanka sare, iyo jawiga soo noqnoqda.

Marka la eego qiimayaasha TG ee agabka FR4

Substrate FR-4 waa nidaamka resin epoxy, sidaa darteed muddo dheer, qiimaha Tg waa tusaha ugu caansan ee loo isticmaalo in lagu kala saaro darajada substrate-ka FR-4, sidoo kale waa mid ka mid ah tilmaamayaasha waxqabadka ugu muhiimsan ee qeexitaanka IPC-4101, Tg qiimaha habka resinka, waxa loola jeedaa walxaha ka yimid xaalad adag ama "galaas" si ay si fudud u qalloocan ama u jilciso barta kala-guurka heerkulka gobolka.Isbeddelka heerkulbeegga ah had iyo jeer waa la beddelaa ilaa iyo inta uu xabaggu aanu dumin.Tani waxay ka dhigan tahay in marka walxaha laga soo kululeeyo heerkulka qolka ilaa heerkul ka sarreeya qiimaha Tg, ka dibna la qaboojiyo ka hooseeya qiimaha Tg, waxay ku soo laaban kartaa xaaladdii hore ee adag ee isla sifooyinkaas.

Si kastaba ha ahaatee, marka walaxda lagu kululeeyo heerkul aad uga sarreeya qiimihiisa Tg, isbeddelka xaaladda marxaladda aan la soo celin karin ayaa laga yaabaa inay keento.Saamaynta heerkulkani wuxuu leeyahay wax badan oo ku saabsan nooca maaddooyinka, iyo sidoo kale kala-goynta kulaylka ee resin.Guud ahaan, marka uu sareeyo Tg substrate-ka, ayaa sareeysa kalsoonida maaddada.Haddii habka alxanka-la'aanta ah ee rasaasta la qaato, waa in sidoo kale la tixgeliyaa heerkulka kala-goynta kulaylka (Td) ee substrate-ka.Tilmaamayaasha waxqabadka kale ee muhiimka ah waxaa ka mid ah iskudar ballaarinta kulaylka (CTE), nuugista biyaha, sifooyinka adhesion ee maaddada, iyo tijaabooyinka wakhtiga lakabka ee inta badan la isticmaalo sida imtixaanada T260 iyo T288.

Farqiga ugu cad ee u dhexeeya alaabta FR-4 waa qiimaha Tg.Marka loo eego heerkulka Tg, FR-4 PCB guud ahaan waxaa loo qaybiyaa Tg hoose, Tg dhexdhexaad ah iyo taarikada Tg sare.Warshadaha, FR-4 oo leh Tg agagaarka 135 ℃ waxaa badanaa lagu sifeeyaa Tg PCB hooseeya;FR-4 qiyaastii 150 ℃ ayaa loo beddelay Tg PCB dhexdhexaad ah.FR-4 oo leh Tg qiyaastii 170 ℃ ayaa loo kala saaray inuu yahay Tg PCB sare.Haddii ay jiraan wakhtiyo badan oo cadaadis ah, ama lakabyada PCB (in ka badan 14 lakab), ama heerkulka alxanka sare (≥230 ℃), ama heerkulka shaqada oo sarreeya (in ka badan 100 ℃), ama cadaadiska alxanka sare (sida alxanka hirarka), Tg PCB sare waa in la doortaa.

FAQs

1.ENIG ma ka fiican yahay HASL?

Isku-dhafkan xooggani wuxuu sidoo kale ka dhigayaa HASL dhammaystir wanaagsan codsiyada kalsoonida sare leh.Si kastaba ha ahaatee, HASL waxay ka tagtaa dusha sare ee aan sinnayn in kasta oo habka la siman yahay.ENIG, dhanka kale, waxay bixisaa oog aad u fidsan taasoo ka dhigaysa ENIG mid door bidaya garoon wanaagsan iyo qaybaha tirinta biinanka sare gaar ahaan aaladaha kubbada-grid array (BGA).

2.Waa maxay agabka caadiga ah ee leh TG sare ee Lianchuang isticmaalay?

Waxyaabaha caadiga ah ee leh TG sare ee aan isticmaalnay waa S1000-2 iyo KB6167F, iyo SPEC.sida soo socota,
