Nrog rau kev loj hlob sai ntawm cov khoom siv hluav taws xob thiab hluav taws xob sib txuas lus, ultra-thick tooj liab ntawv ci Circuit Court boards ntawm 12oz thiab saum toj no tau maj mam dhau los ua ib yam tshwj xeeb PCB boards nrog rau kev lag luam dav dav, uas tau nyiam ntau thiab ntau tus neeg tsim khoom thiab kev saib xyuas;Nrog rau kev siv dav ntawm cov ntawv luam tawm hauv Circuit Court hauv hluav taws xob, kev ua haujlwm yuav tsum ...
- Kawm Txog Ntau Hom PCBs thiab Lawv Qhov Zoo
Lub rooj tsavxwm luam tawm (PCB) yog ib lub rooj tsavxwm nyias ua los ntawm fiberglass, epoxy, lossis lwm yam ntaub ntawv laminate.PCBs muaj nyob rau hauv ntau yam khoom siv hluav taws xob thiab hluav taws xob xws li beepers, xov tooj cua, radars, computer systems, thiab lwm yam. Ntau hom PCBs yog siv raws li cov ntawv thov.Dab tsi yog ntau hom PCBs?Nyeem ntxiv kom paub.Dab tsi yog qhov txawv ntawm PCBs?PCBs feem ntau yog ...
- Comparative Tracking Index ntawm PCB
Kev taug qab tsis kam ntawm tooj liab clad laminate feem ntau yog qhia los ntawm kev sib piv kev ntsuas ntsuas (CTI).Ntawm ntau yam khoom ntawm tooj liab clad laminates (tooj liab clad laminates luv luv), nrhiav kev tiv thaiv, raws li qhov tseem ceeb ntawm kev nyab xeeb thiab kev ntseeg siab, tau nce nqi los ntawm PCB Circuit board designers thiab circuit board manufacturers.Tus nqi CTI raug kuaj raws li ...
- PCB Pad loj
Thaum tsim PCB pads hauv PCB board tsim, nws yog ib qho tsim nyog yuav tsum tsim kom nruj raws li cov kev cai thiab cov qauv.Vim tias nyob rau hauv SMT thaj ua haujlwm, kev tsim ntawm PCB ncoo tseem ceeb heev.Tus tsim ntawm lub ncoo yuav cuam tshuam ncaj qha rau cov solderability, stability thiab kub hloov ntawm cov khoom.Nws muaj feem xyuam rau qhov ua tau zoo ntawm kev ua thaj chaw.Tom qab ntawd dab tsi yog PC ...
- Daim phiaj tooj liab, khoom tooj liab.Qhov twg?
Copper txheej yog dab tsi?Lub npe hu ua tooj liab ncuav yog siv qhov chaw tsis siv ntawm PCB ua qhov chaw siv thiab tom qab ntawd sau nrog cov khoom tooj liab.Cov chaw tooj liab no tseem hu ua tooj liab filling.Qhov tseem ceeb ntawm cov txheej tooj liab yog txhawm rau txo qhov impedance ntawm cov xaim hauv av thiab txhim kho lub peev xwm tiv thaiv kev cuam tshuam;txo qhov hluav taws xob poob thiab txhim kho kev ua haujlwm ntawm lub zog hluav taws xob;yog tias ...
- Yuav ua li cas tswj Circuit Court board warpage & twist
Warping ntawm lub roj teeb Circuit Court board yuav ua rau qhov chaw tsis raug ntawm cov khoom;Thaum lub rooj tsavxwm yog khoov rau hauv SMT, THT, cov khoom siv pins yuav tsis zoo, uas yuav ua rau muaj teeb meem ntau rau kev sib dhos thiab kev teeb tsa.IPC-6012, SMB-SMT Printed circuit boards muaj qhov siab tshaj plaws warpage los yog twist ntawm 0.75%, thiab lwm yam boards feem ntau tsis tshaj 1.5%;qhov tso cai warpage (ob npaug ...
- Vim li cas cov ntawv luam tawm Circuit Board xav tau kev tswj hwm impedance?
Vim li cas cov ntawv luam tawm Circuit Board xav tau kev tswj hwm impedance?Hauv cov kab hluav taws xob xaim hluav taws xob ntawm cov khoom siv hluav taws xob, qhov kev tiv thaiv tau ntsib thaum lub teeb liab siab lossis hluav taws xob yoj propagates hu ua impedance.Vim li cas PCB boards yuav tsum tau impedance thaum lub sij hawm tsim cov txheej txheem ntawm Circuit Court board Hoobkas?Cia peb txheeb xyuas los ntawm 4 yam hauv qab no: 1. Lub Rooj Tswjhwm Saib PCB ntawm ...
- Vim li cas feem ntau cov txheej txheem Circuit Court boards yog cov khaubncaws sab nraud povtseg?
Muaj ib sab, ob sab thiab ntau txheej Circuit Court boards.Tus naj npawb ntawm ntau txheej boards tsis txwv.Tam sim no muaj ntau tshaj 100-txheej PCBs.Cov txheej txheem ntau txheej PCB yog plaub txheej thiab rau txheej boards.Tom qab ntawd vim li cas tib neeg thiaj li muaj lus nug "Vim li cas PCB multilayer boards tag nrho cov txheej txheem txawm tias tus lej?
