Kev soj ntsuam ntawm qhov ua rau ntawm Printed Circuit Board Drilling tshaj qhov kam rau ua

Printed circuit board drilling tshaj qhov kam rau ua yog hais txog qhov sib txawv ntawm qhov drilling loj los ntawm qhov yuav tsum tau ua. Muaj ntau yam uas tuaj yeem ua rau qhov sib txawv ntawm qhov drilling, xws li cov khoom siv, cov khoom siv tho, cov ntawv txhuas, thiab cov ntaub qhwv, uas tuaj yeem cuam tshuam qhov tseeb ntawm qhov drilling.

1. Cov khoom siv

Cov ntaub ntawv sib txawv ntawm cov khoom siv hluav taws xob muaj qhov cuam tshuam loj heev rau kev hnav ntawm lub tshuab drilling, feem ntau raws li cov khoom siv ob sab (plaub daim ib pawg), 2500-3000 qhov tuaj yeem drilled; 500 qhov tuaj yeem tau laum rau ntawm high-density multi-layer boards; Rau FR-4 (peb blocks ib pawg), 2500 qhov tuaj yeem tho; Rau nyuaj FR-4 cov ntaub ntawv Tg siab, qhov nruab nrab qhov txo qis yog 30-40 feem pua ​​. Yog hais tias Tg siab, lub modulus siab, lub rigidity yog zoo, lub warpage yog me me, tab sis lub brittleness yog loj, thiab hnav ntawm lub laum taub yuav nce. Kev tswj tsis raug thiab kev hnav ntau dhau ntawm qhov drilling nozzle tuaj yeem ua rau lub qhov sib txawv thiab cov phab ntsa ntawm lub qhov ntxhib, thiab hauv cov xwm txheej hnyav, lub phaj tuaj yeem tawg.

Kev cuam tshuam ntawm tooj liab thickness, board thickness, thiab iav yarn ntawm drilling ntawm Circuit Court boards: Txiav tuab heev tooj liab rau hauv cov duab hlau cuam tshuam rau kev tso tawm ntawm cov ntaub ntawv txiav thiab roughness ntawm lub qhov phab ntsa. Cov xov paj iav yog qhov tseem ceeb cuam tshuam rau kev hnav ntawm lub laum me ntsis, thiab hnav cov laum ntau dhau yuav ua rau muaj kev cuam tshuam rau qhov tshwm sim ntawm qhov sib txawv. Lub phaj tuab dua, qhov hnyav dua qhov hnav, yog li kev sib tsoo ntawm lub laum me ntsis yuav yog qhov tseem ceeb.

2. Aluminium ntawv

Drilled aluminium ntawv rau Circuit Court boards feem ntau yog nyob ib ncig ntawm 0.17mm tuab, nrog ib tug tej yam nto hardness los tiv thaiv burrs nyob rau saum npoo ntawm lub qhov drilled; Nws tseem yuav tsum tau muaj qee qhov ntawm elasticity, uas tam sim ntawd deforms thaum lub laum me ntsis los rau hauv kev sib cuag nrog lub laum me ntsis, tso cai rau lub laum me ntsis kom raug raws li txoj hauj lwm drilled, kom ntseeg tau qhov tseeb ntawm qhov drilling txoj hauj lwm. Qhov wrinkling ntawm cov ntawv txhuas thiab kev suav nrog ntawm cov ntawv txhuas thiab cov rooj sib tham hauv Circuit Court tuaj yeem cuam tshuam rau qhov adhesion thiab kev sib txuas ntawm cov ntawv txhuas thiab cov khoom siv hluav taws xob hauv Circuit Court, ua rau burrs. Thaum cov burrs raug tsim, cov tsa burrs nqa cov ntawv txhuas, cais lawv ntawm lub rooj tsavxwm, thiab ua rau cov burrs loj hlob mus rau thaj tsam ib puag ncig. Qhov no yog qhov tsis siv neeg diffusion ntawm burrs. Thaum cov burrs diffuse, cov hmoov av sib xyaw ntawm cov phaj thiab cov ntawv txhuas thaum lub sij hawm tshem tawm cov nti yuav yuam kom lub drilling nozzle hloov qhov drilling txoj hauj lwm, thaum kawg ua rau deviation thiab breakage ntawm drilling nozzle.

3.Pib phaj

Feem ntau siv drilling ncoo rau Circuit Court boards ntawm FR-4 cov ntaub ntawv yog cov khoom siv hauv tsev, uas tuaj yeem muab faib ua qhov nruab nrab thiab qhov ntom ntom. Ib lub ncoo zoo tuaj yeem zam kev hnav ntau dhau ntawm lub laum hniav, vim tias lub laum taub tig thiab rubs ntawm kev kub ceev hauv lub ncoo, ua rau lub laum hniav hnav. Yog hais tias impurities muaj nyob rau hauv lub ncoo, nws yuav ua rau kom qhov hnav ntawm lub laum hniav. Muaj qhov zoo ntawm qhov tawv tawv, flatness, thiab tsawg impurities yog qhov yuav tsum tau ua rau cov phaj rov qab.

4. Drill ntsis

Kev xaiv tsis raug ntawm cov khoom siv laum kuj yog ib qho laj thawj rau kev ua siab ntev ntawm cov ntawv luam tawm Circuit Board drilling. Cov khoom siv, txoj kab uas hla, lub kaum ntse ntse, txiav groove thiab lwm yam ntawm cov laum me ntsis yuav cuam tshuam ncaj qha rau qhov drilling zoo. Yog tias qhov kev xyaum tsis raug xaiv raug xaiv, nws yog qhov yooj yim rau qhov drilling kom dhau qhov kam rau ua.

Tsis tas li ntawd, kev tswj tsis raug ntawm cov txheej txheem drilling kuj tuaj yeem ua rau cov ntawv luam tawm Circuit Court board drilling ntau tshaj qhov kam rau ua. Cov txheej txheem drilling yuav tsum muaj kev tswj xyuas nruj xws li kev sib hloov ceev, pub ceev, thiab txiav lubrication. Yog tias cov xwm txheej no tsis raug kho kom tsim nyog, lawv yuav ua rau muaj kev cuam tshuam tsis zoo rau qhov zoo ntawm qhov drilling, ua rau cov xwm txheej ntawm kev ua siab ntev tshaj.

Sihui Fuji tsis tu ncua ntxiv dag zog rau kev tswj hwm los ntawm tsib qhov ntev ntawm tib neeg, tshuab, khoom siv, txheej txheem, thiab ib puag ncig (5M), suav nrog cov neeg ua haujlwm, tshuab, khoom siv, drilling tsis, txoj kev, kub, av noo, voltage, thiab lwm yam, los xyuas kom meej tias cov khoom drilled ua tau raws li cov neeg siv khoom xav tau.
