PCB pawg thawj coj saib Kev tsim khoom yog cov chaw tsim khoom ntawm cov ntawv luam tawm Circuit Board. Rhyming yog ib qho ntawm cov tuam txhab PCB hauv Suav teb nrog 10 xyoo ntawm kev tsim khoom PCB. PCB nta 1-36 txheej.

Ntawm RayMing, peb ua cov txheej txheem sab hauv kom ntseeg tau tias qhov ua tau zoo ntawm peb cov haujlwm tau ntsib thiab tshaj li peb cov neeg siv khoom xav tau. The RayMing team uses the latest PCB manufacturing technology and equipment to meet the demand for quality. Peb kev cog lus los muab cov khoom lag luam PCB zoo thiab cov kev pabcuam tau pab peb yeej txoj kev ntseeg siab thiab hwm ntawm peb cov neeg siv khoom.

Peb niaj hnub siv zog los tsim cov kev daws teeb meem tshiab, peb tsis muaj lub dag zog los yuav qhov kev tsim khoom tshiab PCB pawg thawj coj saib thev naus laus zis thiab kev paub txog kev ua haujlwm. Qhov no tso peb rau hauv txoj haujlwm muaj zog los muab cov kev pabcuam thawj zaug los ntawm PCB kev tsim khoom los ua ke, ntsuas, thiab xa khoom.

Cov txheej txheem tsim khoom PCB

Thawj: PCB zaj duab xis tsim

Txhua txheej tooj liab thiab txheej txheej tiv taus yog ua los ntawm cov duab nthuav tawm zaj duab xis polyester. Peb tsim cov yeeb yaj kiab no los ntawm koj cov ntaub ntawv tsim, tsim kom raug (1: 1) cov yeeb yam sawv cev ntawm koj tsim. Thaum xa daim ntawv Gerber, txhua tus neeg Gerber cov ntaub ntawv sawv cev ib txheej ntawm PCB pawg thawj coj.

Qhov thib ob: PCB xaiv cov khoom siv raw

Kev lag luam-tus qauv 1.6 hli tuab FR-4 laminated tooj liab cladding ntawm ob sab. Lub vaj huam sib luag loj yuav haum rau ntau lub laug cam.

Thib peb: PCB drilling

Tsim qhov dhau los-qhov xav tau rau PCB tsim los ntawm koj cov ntaub ntawv xa, siv NC xyaum thiab carbide ntsis.

Zaum plaub: PCB tsis muaj tooj liab electroplated

Cov txheej txheej nyias nyias ntawm tooj liab tau tso rau hauv qhov dhau los txhawm rau txuas hluav taws xob rau txheej sib txawv ntawm PCB. Cov tooj liab no tau ua kom tuab los ntawm electroplating (Kauj Ruam 6).

Thib tsib: PCB daim ntawv thov photoresist thiab duab

To transfer PCB designs from electronic CAD data to physical boards, we first applied photosensitive photoresist to the panel, covering the entire board area. The copper film image (Step 1) is then placed on the plate and the uncovered portion of the photoresist is exposed by a high-intensity UV light source. Peb tom qab ntawd tsim kho cov phiaj xwm hluav taws xob (tshem tawm cov duab tsis pom los ntawm lub vaj huam sib luag) los tsim cov ntaub qhwv thiab txuas.

Thib rau: PCB qauv pawg thawj coj saib

Cov kauj ruam no yog txheej txheem hluav taws xob hluav taws xob uas tsim cov tuab tooj liab mus rau saum npoo ntawm lub qhov thiab PCB. Thaum cov tooj liab tuab tau tsim nyob rau hauv Circuit Court thiab lub qhov, peb npog lub ntsej muag nthuav tawm nrog txheej ntxiv ntawm cov tin. Cov tin yuav tiv thaiv cov tooj liab plating thaum txheej txheem txheej txheem (Kauj Ruam 7) thiab tom qab ntawd raug tshem tawm.

Tshooj 7: PCB sawb & AMP; PCB etching

This process takes place in several steps. Thawj yog tshuaj tshem tawm (tshem tawm) ntawm photoresist los ntawm lub vaj huam sib luag. Cov tooj liab uas tau nthuav tawm tshiab yog tom qab tshuaj lom (tshem tawm) los ntawm lub vaj huam sib luag. Cov tin tau thov hauv qib 6 tiv thaiv qhov xav tau tooj liab Circuit Court los ntawm kev kos. Txij ntawm no mus, cov txheej txheem yooj yim ntawm PCB tau teev tseg. Finally, chemical removal (stripping) of the tin protective layer exposes the copper circuit.

8th: PCB daim npog qhov ncauj

Tom ntej no, peb tau npog tag nrho cov vaj huam sib luag nrog cov kua ua kom tsis zoo. Siv cov zaj duab xis nyias thiab siv lub teeb UV siab (zoo ib yam li qib 5), peb nthuav tawm thaj chaw weldable ntawm PCB. Lub luag haujlwm tseem ceeb ntawm lub npog ntsej muag yog txhawm rau tiv thaiv feem ntau ntawm cov tooj liab Circuit Court los ntawm oxidation, puas tsuaj, thiab xeb, thiab tswj kev sib cais ntawm Circuit thaum sib dhos.

Tom ntej no, peb tau luam tawm cov cim siv, logo, thiab lwm yam ntaub ntawv muaj nyob hauv cov ntawv hluav taws xob mus rau ntawm lub vaj huam sib luag. Cov txheej txheem no zoo ib yam li txheej txheem luam ntawv inkjet tab sis tau tsim tshwj xeeb rau PCBS

Lub sijhawm thib 10: Kev kho PCB nto

Thaum kawg, qhov ua tiav saum npoo yog siv rau lub vaj huam sib luag. Qhov ua tiav no (tin/lead solder lossis silver-impregnated, kub-plated) yog siv los tiv thaiv tooj liab (weldable nto) los ntawm oxidation thiab ua ib feem rau txoj haujlwm ntawm PCB.

11th: PCB kev tsim khoom

Qhov kawg, tab sis tsis tsawg kawg, peb siv NC cov cuab yeej txhawm rau txhawm rau PCB ib puag ncig los ntawm lub vaj huam sib luag loj. PCB boards are now finished and will be shipped to you soon.

Qhov no yog ib leeg ib sab PCB thiab ob tog ua PCB txheej txheem tsim khoom, txheej txheej txheej txheej txheej txheej txheej PCB tsim yuav muaj ntau dua. Nias lamination yog xav tau.

Tom qab 11 txheej txheem tsim khoom PCB, peb yuav ua 100% kev ntsuas hluav taws xob ntawm koj lub rooj tsav xwm PCB.
