Competitive PCB Chaw tsim tshuaj paus

Los ntawm lub xyoo pua 20th mus rau thaum pib ntawm lub xyoo pua 21st, lub Circuit Court board electronics kev lag luam yog druing lub sij hawm sai sai ntawm technology, hluav taws xob technology tau sai heev.Raws li kev lag luam luam tawm Circuit Board, tsuas yog nrog nws txoj kev txhim kho synchronous, tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom tas li.Nrog rau qhov me me, lub teeb thiab nyias ntim ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob luam tawm tau tsim lub rooj tsav xwm hloov tau yooj yim, lub rooj tsav tsheb tsis yooj yim, lub qhov muag tsis pom qhov faus qhov Circuit Court board thiab lwm yam.

Tham txog qhov muag tsis pom / faus qhov, peb pib nrog ib txwm muaj ntau txheej.Cov txheej txheem ntau txheej txheej Circuit Court board yog tsim los ntawm sab hauv thiab sab nraud Circuit Court, thiab cov txheej txheem ntawm drilling thiab metalization hauv lub qhov yog siv los ua kom tiav cov haujlwm ntawm kev sib txuas sab hauv ntawm txhua txheej txheej.Txawm li cas los xij, vim qhov nce ntawm kab ntom, cov ntim ntim ntawm cov chaw yog hloov tas li.Txhawm rau ua kom lub rooj tsav xwm hauv Circuit Court txwv tsis pub dhau thiab tso cai rau ntau thiab ntau dua qhov kev ua tau zoo, ntxiv rau cov kab dav dav, lub aperture tau raug txo los ntawm 1 hli ntawm DIP jack aperture mus rau 0.6 hli ntawm SMD, thiab ntxiv txo kom tsawg dua. 0.4mm ib.Txawm li cas los xij, thaj chaw saum npoo yuav tseem nyob, yog li faus qhov thiab qhov qhov muag tsis pom tuaj yeem tsim tawm.Lub ntsiab txhais ntawm faus qhov thiab qhov muag tsis pom qhov yog raws li nram no:

Builed qhov:

Qhov los ntawm lub qhov nruab nrab ntawm cov txheej sab hauv, tom qab nias, tsis tuaj yeem pom, yog li nws tsis tas yuav tsum nyob hauv thaj chaw sab nrauv, sab sauv thiab sab hauv ntawm lub qhov yog nyob rau sab hauv txheej ntawm lub rooj tsavxwm, hauv lwm lo lus, faus rau hauv lub lub rooj tsavxwm

Qhov muag qhov muag:

Nws yog siv rau kev sib txuas ntawm cov txheej txheej saum npoo thiab ib lossis ntau txheej sab hauv.Ib sab ntawm lub qhov yog ntawm ib sab ntawm lub rooj tsavxwm, thiab tom qab ntawd lub qhov yog txuas nrog rau sab hauv ntawm lub rooj tsavxwm.

Qhov zoo ntawm lub qhov muag tsis pom thiab faus qhov board:

Hauv kev siv tshuab tsis yog perforating, daim ntawv thov ntawm qhov muag tsis pom qhov thiab qhov faus tuaj yeem txo qhov luaj li cas ntawm PCB, txo cov txheej txheem, txhim kho cov khoom siv hluav taws xob, ua kom cov khoom siv hluav taws xob zoo dua qub, txo tus nqi, thiab tseem ua rau cov qauv tsim. ua hauj lwm yooj yim dua thiab ceev.Hauv kev tsim PCB ib txwm siv thiab ua tiav, dhau ntawm qhov tuaj yeem ua rau muaj ntau yam teeb meem.Ua ntej, lawv nyob hauv ntau qhov chaw zoo.Qhov thib ob, ntau qhov dhau ntawm-qhov nyob rau hauv qhov chaw ntom ntom kuj ua rau muaj kev cuam tshuam loj rau kev xaim ntawm cov txheej sab hauv ntawm ntau txheej PCB.Cov no los ntawm qhov nyob hauv qhov chaw xav tau rau kev xaim, thiab lawv dhau los ntawm qhov chaw ntawm lub zog hluav taws xob thiab cov xaim hauv av, uas yuav rhuav tshem cov yam ntxwv impedance ntawm cov khoom siv hluav taws xob hauv av xaim txheej thiab ua rau tsis ua haujlwm ntawm cov khoom siv hluav taws xob hauv av. txheej.Thiab cov cuab yeej siv tshuab drilling yuav yog 20 npaug ntau npaum li kev siv cov tshuab tsis siv lub tshuab.
