Kev faib tawm thiab kev txheeb xyuas tus yam ntxwv of PCB qhov tsis muaj tooj liab

Kev faib tawm thiab cov yam ntxwv ntawm qhov tsis muaj tooj liab

1. Tsis muaj tooj liab hauv PTH lub qhov: Cov txheej txheem hluav taws xob ntawm cov phaj tooj liab ntawm qhov chaw yog qhov sib xws thiab zoo ib yam, thiab cov txheej txheem hluav taws xob ntawm lub phaj hauv lub qhov yog faib sib npaug ntawm lub qhov mus rau qhov tawg. Tom qab kev sib txuas hluav taws xob, qhov tawg yog npog los ntawm cov txheej txheem hluav taws xob.

2. Tsis muaj tooj liab nyob rau hauv tooj liab nyias qhov ntawm lub rooj tsavxwm:

(1) Tsis muaj tooj liab nyob rau hauv cov hluav taws xob tooj liab nyias qhov ntawm tag nrho cov board – cov hluav taws xob txheej ntawm cov tooj liab nto thiab lub qhov tooj liab daim hlau nyias nyias. Daim duab hluav taws xob txheej encased;

(2) Tsis muaj tooj liab nyob rau hauv lub qhov nyias nyias ntawm cov hluav taws xob tooj liab hauv lub qhov – cov txheej txheem hluav taws xob ntawm lub phaj tooj liab yog qhov sib xws thiab ib txwm muaj, thiab cov hluav taws xob txheej ntawm lub qhov hauv lub qhov qhia tau hais tias txo qis ntawm kev sib tsoo los ntawm cov lub qhov mus rau qhov tawg, thiab qhov tawg feem ntau yog nyob rau hauv nruab nrab ntawm lub qhov. Copper txheej sab laug

Txoj cai muaj zoo uniformity thiab symmetry, thiab qhov tawg yog them los ntawm cov hluav taws xob txheej tom qab cov duab hluav taws xob.

3. Kho qhov tawg:

(1) Kev tshuaj xyuas tooj liab thiab kho qhov tawg-cov txheej txheem hluav taws xob ntawm lub phaj tooj liab yog qhov sib xws thiab zoo ib yam, cov txheej txheem hluav taws xob ntawm lub qhov phaj tooj liab tsis muaj qhov ua kom ntse, thiab qhov tawg yog qhov tsis sib xws, uas yuav tshwm sim hauv lub qhov lossis nyob rau hauv nruab nrab ntawm lub qhov, thiab feem ntau tshwm sim nyob rau hauv lub qhov phab ntsa Rough pob thiab lwm yam tsis xws luag, lub pob txha yog them los ntawm cov hluav taws xob txheej tom qab qhov hluav taws xob kev twb kev txuas.

(2) Kev tshuaj xyuas corrosion thiab kho ntawm qhov chaw zais-cov txheej txheem hluav taws xob ntawm lub phaj tooj liab yog zoo ib yam thiab zoo ib yam, cov txheej txheem hluav taws xob ntawm lub qhov phaj tooj liab tsis muaj qhov yuav ua kom ntse, thiab cov pob txha tawg tsis zoo, uas yuav tshwm sim hauv lub qhov los yog nyob rau hauv nruab nrab ntawm lub qhov, thiab feem ntau tshwm nyob rau hauv lub qhov phab ntsa Rough pob thiab lwm yam tsis xws luag, cov hluav taws xob txheej ntawm lub pob txha yog tsis them los ntawm hluav taws xob txheej ntawm lub rooj tsavxwm.

4. Tsis muaj tooj liab hauv lub qhov ntsaws: Tom qab daim duab yog electro-etched, muaj cov khoom pom tseeb daig hauv lub qhov, feem ntau ntawm lub qhov phab ntsa yog etched, thiab daim duab hluav taws xob txheej ntawm qhov tawg tsis npog hluav taws xob. txheej ntawm lub rooj tsavxwm.

5. Tsis muaj tooj liab nyob rau hauv lub qhov hluav taws xob: cov hluav taws xob txheej ntawm qhov tawg tsis npog cov hluav taws xob txheej ntawm lub rooj tsavxwm – lub thickness ntawm cov hluav taws xob txheej thiab cov hluav taws xob txheej ntawm lub rooj tsavxwm yog uniform, thiab cov tawg yog uniform; cov txheej txheem hluav taws xob zoo li ntse kom txog thaum nws ploj mus, thiab cov txheej txheem hluav taws xob ntawm lub rooj tsavxwm Cov txheej txheem dhau ntawm cov txheej txheem hluav taws xob thiab txuas ntxiv mus rau ib qho kev ncua deb ua ntej yuav raug txiav.

Kev txhim kho kev taw qhia:

1. Kev ua haujlwm (saib saum toj thiab qis dua, kev teeb tsa parameter, kev saib xyuas, kev tuav tsis zoo);

2. Cov khoom siv (crane, feeder, cua sov cwj mem, vibration, twj tso kua mis, filtration voj voog);

3. Cov khoom siv (phaj, potions);

4. Cov txheej txheem (tsis, txheej txheem, txheej txheem thiab kev tswj kom zoo);

5. Ib puag ncig (variation tshwm sim los ntawm qias neeg, ntxhov thiab ntxhov).

6. Kev ntsuas (kev kuaj tshuaj, tshuaj xyuas tooj liab thiab kuaj pom qhov muag).
