Dab tsi yog PCB plug qhov txheej txheem

Raws li qhov kev pom zoo tias cov khoom siv hluav taws xob zoo li muaj ntau yam kev ua haujlwm thiab kev ua haujlwm, cov kab sib nrug ntawm PCB boards tau txais me me thiab me, thiab qhov ceev ntawm cov teeb liab kis tau tus mob kuj zoo dua. High-density integration (HDI) thev naus laus zis tuaj yeem ua rau kev tsim cov khoom kawg ntau me me. Piv nrog rau cov txheej txheem PCB, HDI Circuit Court boards siv cov kab dav dav / qhov sib txawv (tsawg dua lossis sib npaug li 2/2 mil), me dua vias (<0.15mm) and="" pads=""><0.4 mm),="" and="" higher="" pad="" density="" (="">20 daim / cm2). Qhov nyob hauv disk feem ntau yog siv hauv HDI boards, thiab lub qhov nyob hauv disk yuav tsum muaj tag nrho, yog li qhov yuav tsum tau ua rau lub qhov nyob hauv disk tau nce siab dua. Xws li: tsis muaj solder resist number case yuav tsum nkag mus rau hauv lub qhov, ua rau tin hlaws dai rau hauv lub qhov. Thaum lub PCB yog yoj soldered, lub tin yuav dhau los ntawm cov khoom nto ntawm lub qhov los ua ib qho luv luv Circuit Court; tsis muaj roj tawg, ua rau SMT soldering, thiab lwm yam.

Ink plug qhov: Tus number case plug qhov yog siv los ntawm qhov hauv PCB. Tom qab lub qhov ntsaws, qhov saum npoo yog number case thiab yuav tsis ua hluav taws xob. Feem ntau, cov kev xav tau tom qab ntsaws lub qhov: A. Nws yuav tsum tau ntsaws tag nrho; B. Yuav tsum tsis txhob muaj qhov liab liab lossis cuav tooj liab; C. Nws yuav tsum tsis txhob tag nrho thiab cov protrusions yuav tsum siab tshaj cov ntaub qhwv yuav tsum tau welded nyob ib sab ntawm nws (nws yuav cuam tshuam rau SMT installation). muab tshuaj txhuam).

Resin plug qhov (POFV): Cov resin plug qhov tsuas yog txhais tau hais tias tom qab lub qhov phab ntsa yog plated nrog tooj liab, lub qhov ntawm lub qhov yog sau nrog epoxy resin, nto yog polished, thiab ces lub nto yog plated nrog tooj liab, uas yog kim heev.

Qhov muag tsis pom qhov (HDI) puab txheej resin plug qhov:

Rau qee qhov qhov muag tsis pom ntawm cov khoom, vim tias qhov tuab ntawm qhov muag tsis pom ntawm txheej yog ntau dua 0.5mm, qhov muag tsis pom ntawm qhov tsis tuaj yeem sau los ntawm nias PP kua nplaum, thiab cov resin plugging kuj yuav tsum tau sau cov qhov muag tsis pom los ntawm kev zam. tooj liab-dawb qhov nyob rau hauv qhov muag tsis pom vias nyob rau hauv cov txheej txheem tom ntej. lus nug.

Qhov txawv ntawm resin plug qhov thiab ntsuab roj plug qhov:

Ua ntej cov txheej txheem txuas txuas tau nrov, PCB cov tuam txhab feem ntau tau txais cov txheej txheem txuas nrog cov txheej txheem yooj yim, tab sis cov roj ntsuab ntsaws yuav poob qis tom qab kho, uas ua rau muaj teeb meem ntawm huab cua hauv huab cua, uas tsis tuaj yeem ua raws li tus neeg siv khoom. siab plumpness. Xav tau. Cov txheej txheem txuas cov resin siv cov resin los ntsaws qhov qhov muag tsis pom kev thiab tom qab ntawd nias lawv, uas zoo kawg nkaus daws cov teeb meem tshwm sim los ntawm cov roj ntsuab ntsaws qhov, thiab sib npaug ntawm cov thickness tswj ntawm cov xovxwm-haum dielectric txheej thiab cov txheej sab hauv qhov muag tsis pom qhov txhaws. kev tsis sib haum xeeb ntawm. Txawm hais tias cov txheej txheem resin plugging yog qhov nyuaj hauv cov txheej txheem thiab tus nqi siab, nws muaj ntau qhov zoo dua li tus number case plugging nyob rau hauv cov nqe lus ntawm fullness thiab plugging zoo.
