Hauv qhov blog no, peb yuav tham txog cov txheej txheem kev sib txuas uas siv rau hauv kev sib dhos nruj-flex PCB thiab yuav ua li cas lawv txhim kho tag nrho cov kev ntseeg siab thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob no.
Soldering thev naus laus zis plays lub luag haujlwm tseem ceeb hauv cov txheej txheem sib dhos ntawm rigid-flex PCB. Cov boards tshwj xeeb no yog tsim los muab kev sib xyaw ua ke ntawm kev nruj thiab kev yooj yim, ua rau lawv zoo tagnrho rau ntau yam kev siv uas qhov chaw muaj kev txwv lossis kev sib cuam tshuam nyuaj.
1. Nto mount thev naus laus zis (SMT) nyob rau hauv nruj flex PCB raug:
Surface mount technology (SMT) yog ib qho ntawm cov cuab yeej siv dav tshaj plaws hauv kev sib dhos-flex PCB. Cov txheej txheem yuav tsum tau muab cov khoom siv saum npoo av rau ntawm lub rooj tsavxwm thiab siv cov tshuaj txhuam los tuav lawv rau hauv qhov chaw. Solder paste muaj cov khoom me me uas raug tshem tawm hauv flux uas pab hauv cov txheej txheem soldering.
SMT enables siab tivthaiv ntom ntom ntom ntom, tso cai ntau ntawm cov khoom siv yuav tsum tau nce rau ob tog ntawm ib pcb. Cov thev naus laus zis kuj tseem muab kev ua haujlwm zoo dua thermal thiab hluav taws xob vim yog luv luv conductive paths tsim ntawm cov khoom. Txawm li cas los xij, nws yuav tsum muaj kev tswj xyuas meej ntawm cov txheej txheem vuam los tiv thaiv cov txuas txuas txuas lossis cov pob qij txha tsis txaus.
2. Los ntawm-qhov tshuab (THT) hauv nruj flex PCB facbrication:
Txawm hais tias cov khoom siv saum npoo av feem ntau yog siv rau ntawm cov PCB rigid-flex, cov khoom siv los ntawm lub qhov tseem yuav tsum tau muaj nyob rau qee kis. Los ntawm-lub qhov thev naus laus zis (THT) suav nrog kev ntxig cov khoom coj mus rau hauv lub qhov ntawm PCB thiab soldering lawv mus rau sab nraud.
THT muab cov neeg kho tshuab lub zog rau PCB thiab ua rau nws muaj zog tiv thaiv kev ntxhov siab thiab kev co. Nws tso cai rau kev ruaj ntseg ntawm cov khoom loj, hnyav dua uas yuav tsis haum rau SMT. Txawm li cas los xij, THT ua rau txoj kev coj mus ntev dua thiab tuaj yeem txwv kev hloov pauv ntawm PCB. Yog li ntawd, nws yog ib qho tseem ceeb heev kom muaj kev sib npaug ntawm SMT thiab THT cov khoom hauv cov qauv PCB nruj.
3. Cua kub leveling (HAL) nyob rau hauv nruj flex PCB ua:
Cov cua kub theem (HAL) yog cov txheej txheem soldering siv los siv cov txheej txheem ntawm solder kom pom cov kab tooj liab ntawm cov tawv-flex PCBs. Cov txheej txheem cuam tshuam nrog kev hla PCB los ntawm kev da dej ntawm cov hlau nplaum thiab tom qab ntawd muab tso rau hauv cov cua kub, uas yuav pab tshem tawm cov solder ntau dhau thiab tsim ib qho chaw tiaj tus.
HAL feem ntau yog siv los ua kom muaj kev sib raug zoo ntawm cov khoom siv tooj liab thiab muab cov txheej txheem tiv thaiv oxidation. Nws muab kev pabcuam zoo tag nrho thiab txhim kho kev sib koom ua ke kev ntseeg tau. Txawm li cas los xij, HAL tej zaum yuav tsis haum rau txhua qhov nruj-flex PCB tsim, tshwj xeeb tshaj yog cov uas muaj qhov tseeb lossis kev sib txuas ua ke.
4. Kev xaiv vuam nyob rau hauv nruj flex PCB ua:
Selective soldering yog cov txheej txheem siv los xaiv cov khoom tshwj xeeb rau rigid-flex PCBs. Cov txheej txheem no suav nrog kev siv nthwv dej los yog cov hlau soldering kom raug siv rau cov chaw tshwj xeeb lossis cov khoom siv ntawm PCB.
Kev xaiv soldering yog qhov tshwj xeeb tshaj yog thaum muaj cov khoom siv hluav taws xob, cov khoom sib txuas, lossis cov chaw siab uas tsis tuaj yeem tiv taus qhov kub siab ntawm reflow soldering. Nws tso cai rau kev tswj cov txheej txheem vuam zoo dua thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom rhiab. Txawm li cas los xij, kev xaiv soldering yuav tsum tau teeb tsa ntxiv thiab programming piv rau lwm cov txheej txheem.
Piv txwv li, feem ntau siv vuam technologies rau rigid-flex board sib dhos muaj xws li nto mount technology (SMT), los ntawm lub qhov (THT), cua kub leveling (HAL) thiab xaiv welding.Txhua lub tshuab muaj nws qhov zoo thiab kev txiav txim siab, thiab kev xaiv yog nyob ntawm cov kev cai tshwj xeeb ntawm PCB tsim. Los ntawm kev nkag siab txog cov thev naus laus zis no thiab lawv qhov cuam tshuam, cov tuam txhab tuaj yeem ua kom ntseeg tau thiab ua haujlwm ntawm PCBs nruj-flex hauv ntau yam kev siv.
