Kev tsom xam ntawm tooj liab dawb hauv Printed Circuit Board Holes

Peb txhua tus paub tias tsis muaj tooj liab hauv lub qhov, nws tsis tuaj yeem ua hluav taws xob, uas yuav tsum tau zam hauv kev tsim hluav taws xob hluav taws xob. Muaj ntau ntau yam xwm txheej uas tuaj yeem ua rau tooj liab nkag mus rau hauv PCB qhov, thiab thaum lub sij hawm txheej txheem ntawm kev luam tawm Circuit Board tsim, xws li tooj liab tog, electroplating, drilling, zaj duab xis nias, etching, thiab lwm yam., nws muaj peev xwm ua rau tooj liab. kom tsis muaj nyob hauv lub qhov.

Raws li paub zoo, lub rooj tsavxwm yuav tsum tau ua haujlwm ua ntej kev kho mob vim tias qee qhov substrates yuav raug cuam tshuam los ntawm cov dej noo, lossis qee qhov ntawm cov resin yuav tsis khov kom zoo thaum nias lub substrate synthesized. Qhov no tuaj yeem ua rau qhov tsis zoo ntawm qhov drilling vim qhov tsis txaus lub zog thaum lub sijhawm drilling, ua rau cov plua plav ntau dhau los yog cov phab ntsa ntxhib, burrs hauv lub qhov, tooj liab ntawv ntsia hlau taub hau hauv txheej sab hauv, thiab cov burrs loj heev hauv lub qhov khoob, qhov ntev ntawm qhov. torn seem hauv cheeb tsam fiberglass yog tsis sib npaug. Txwv tsis pub, cov teeb meem no yuav ua rau muaj kev phom sij rau cov tshuaj tooj liab. Tshwj xeeb tshaj yog tom qab qee cov txheej txheem ntau txheej yog laminated, kuj tseem tuaj yeem ua rau tsis zoo resin curing nyob rau hauv substrate cheeb tsam ntawm PP semi-kho nplooj ntawv, uas tuaj yeem cuam tshuam ncaj qha rau drilling thiab ua kom cov tooj liab tso tawm los ntawm kev tshem tawm cov nplaum residue.

Cov teeb meem ua ntej kev kho mob ntawm board. Qee cov laug cam tuaj yeem nqus cov dej noo thiab qee cov resin tuaj yeem ua tsis tau zoo thaum lub sij hawm sib zog ntawm cov substrate. Qhov no tuaj yeem ua rau qhov tsis zoo ntawm qhov drilling, kev sib tsoo ntau dhau, lossis tawg hnyav ntawm cov pob zeb ntawm lub qhov phab ntsa thaum lub sijhawm drilling. Yog li ntawd, qhov tsim nyog ci yuav tsum tau nqa tawm thaum txiav. Tsis tas li ntawd, qee cov txheej txheem ntau txheej kuj tseem tuaj yeem ua rau cov khoom siv tsis zoo nyob rau hauv thaj chaw substrate ntawm PP cov ntawv kho ib nrab tom qab lamination, uas tuaj yeem cuam tshuam ncaj qha rau qhov drilling thiab ua kom cov tooj liab tso tawm los ntawm kev tshem tawm cov nplaum seem. Qhov xwm txheej ntawm qhov drilling yog qhov tsis zoo, feem ntau tshwm sim raws li: muaj ntau cov hmoov av resin hauv lub qhov, lub qhov phab ntsa yog ntxhib, thiab lub qhov ncauj qhov ncauj muaj burrs loj. Burrs nyob rau hauv lub qhov, tooj liab ntawv ntsia hlau taub hau ntawm lub puab txheej, thiab qhov ntev tsis sib xws ntawm lub torn seem nyob rau hauv lub iav fiber ntau muaj peev xwm ua rau txhua yam ua rau muaj kev phom sij rau cov tshuaj tooj liab.

Hauv qhov no, kev tswj hwm tuaj yeem ua tiav los ntawm cov khoom siv thev naus laus zis, khoom siv, kev sim, thiab lwm yam kom txo tau qhov tshwm sim ntawm qhov tsis xws luag.

1. Tsim cov txheej txheem kho kom raug. Nyob rau hauv cov txheej txheem ntawm kev tsim cov ntawv luam tawm Circuit Court boards, nws yog ib qho tsim nyog los tsim cov txheej txheem kom raug, uas yuav tsum tau ua raws li kev soj ntsuam nruj thiab kev txheeb xyuas.

2. Xaiv cov khoom siv thiab cov khoom siv zoo. Xaiv cov neeg muag khoom raug cai thiab cov khoom siv zoo thiab cov khoom siv los xyuas kom meej qhov zoo ntawm cov txheej txheem tooj liab deposition, nrog rau qhov sib npaug ntawm kev tsim khoom thiab kev tswj tus nqi.

3. Ua kom zoo rau cov txheej txheem tooj liab deposition. Kho cov txheej txheem ntawm tooj liab dab dej ntws thiab cov qauv ntawm tooj liab immersion tov kom optimize qhov teeb meem ntawm tsis muaj tooj liab nyob rau hauv lub tooj liab sinking qhov, yog li txhim kho qhov zoo ntawm tooj liab nyob rau hauv lub tooj liab sinking qhov.

4. Txhim khu kev soj ntsuam zoo. Rau kev lag luam PCB, kev ntsuas kev ua tau zoo yog tus yuam sij rau kev ua kom muaj txiaj ntsig zoo. Nws tuaj yeem ntxiv dag zog rau kev sim cov txheej txheem thiab ntxiv dag zog rau kev saib xyuas kom muaj kev tswj xyuas zoo ntawm qhov zoo ntawm cov tooj liab hauv qhov dej.

Sihui Fuji ua raws li qhov ua tau zoo raws li nws lub hauv paus, tsis tu ncua kev tswj hwm los ntawm ntau yam khoom siv xws li tib neeg lub tshuab, cov khoom siv, cov txheej txheem, thiab ib puag ncig, thiab muab cov neeg siv khoom zoo.
