Competitive PCB Chaw tsim tshuaj paus

SMT yog cov ntawv luv rau Surface Mounted Technology, cov thev naus laus zis nrov tshaj plaws thiab cov txheej txheem hauv kev lag luam hluav taws xob sib dhos. Electronic Circuit Surface Mount Technology (SMT) yog hu ua Surface Mount lossis Surface Mount Technology. Nws yog ib yam ntawm Circuit Board los ua ke technology uas txhim kho leadless los yog luv txhuas txhuas nto los ua ke Cheebtsam (SMC / SMD nyob rau hauv Suav) nyob rau saum npoo ntawm Printed Circuit Board (PCB) los yog lwm yam substrate nto, thiab ces welds thiab assembles los ntawm reflow vuam los yog dip vuam.

Feem ntau, cov khoom siv hluav taws xob uas peb siv yog ua los ntawm PCB ntxiv rau ntau yam capacitors, resistors thiab lwm yam khoom siv hluav taws xob raws li daim duab kos, yog li txhua yam khoom siv hluav taws xob xav tau ntau yam SMT chip processing technology.

SMT cov txheej txheem txheej txheem tseem ceeb suav nrog: kev tshuaj ntsuam luam ntawv (lossis xa tawm), mounting (kho), reflow vuam, tu, kuaj, kho.

1. Kev tshuaj ntsuam luam ntawv: Lub luag haujlwm ntawm kev tshuaj ntsuam luam ntawv yog kom xau cov tshuaj nplaum los yog daim nplaum nplaum rau ntawm PCB lub vov tsev los npaj rau kev sib txuas ntawm cov khoom. Cov khoom siv yog tshuaj ntsuam tshuab luam ntawv (screen printing tshuab), nyob rau hauv pem hauv ntej kawg ntawm SMT ntau lawm kab.

2. Cov kua nplaum txau: Nws tso kua nplaum rau ntawm qhov chaw ruaj khov ntawm PCB pawg thawj coj saib, thiab nws lub luag haujlwm tseem ceeb yog kho cov khoom siv rau lub rooj tsav xwm PCB. Cov cuab yeej siv yog lub tshuab xa khoom, nyob rau pem hauv ntej kawg ntawm SMT cov kab ntau lawm lossis tom qab cov khoom siv kuaj.

3. Mount: Nws txoj haujlwm yog txhawm rau txhim kho cov khoom sib dhos saum npoo kom raug rau qhov chaw ruaj khov ntawm PCB. Cov cuab yeej siv yog SMT qhov chaw tshuab, nyob tom qab lub tshuab luam ntawv tshuaj ntsuam hauv SMT ntau lawm kab.

4. Kev kho: Nws txoj haujlwm yog ua kom yaj SMT nplaum kom cov khoom sib dhos saum npoo thiab PCB pawg thawj coj tuaj yeem sib koom ua ke. Cov khoom siv yog curing rauv, nyob tom qab ntawm SMT SMT ntau lawm kab.

5. Reflow welding: kev ua haujlwm ntawm reflow welding yog yaj cov tshuaj txhuam hniav, kom cov khoom sib dhos nto thiab PCB pawg thawj coj ua ke. Cov cuab yeej siv yog reflow vuam rauv, nyob rau hauv SMT ntau lawm kab tom qab SMT tso tshuab.

6. Kev Tu: Lub luag haujlwm yog tshem tawm cov vuam seem xws li flux ntawm lub PCB sib dhos uas tsim kev puas tsuaj rau tib neeg lub cev. Cov cuab yeej siv yog lub tshuab ntxuav, txoj haujlwm tsis tuaj yeem kho, tuaj yeem nyob hauv online, lossis tsis nyob online.

7. Kev Ntsuas: Nws yog siv los kuaj xyuas qhov vuam zoo thiab kev sib dhos zoo ntawm cov khoom sib dhos PCB. Cov cuab yeej siv suav nrog cov iav tsom iav, tsom iav, ntsuas ntsuas hauv online (ICT), ntsuas rab koob ya, tsis siv neeg kho qhov muag (AOI), kuaj X-ray, ntsuas ntsuas kev ua haujlwm, thiab lwm yam. Qhov chaw tuaj yeem teeb tsa hauv qhov tsim nyog. ib feem ntawm cov kab ntau lawm raws li qhov yuav tsum tau ua ntawm kev tshuaj xyuas.

8.Kev Kho: nws yog siv los rov ua haujlwm ntawm PCB uas tau kuaj pom muaj qhov tsis raug. Cov cuab yeej siv yog soldering hlau, kho cov chaw ua haujlwm, thiab lwm yam. Cov kev teeb tsa yog nyob txhua qhov chaw ntawm cov kab ntau lawm.
