uburyo bwo guhuza imbaho ​​ebyiri za pcb

Mwisi yisi ya elegitoroniki nizunguruka, imbaho ​​zicapye zicapye (PCBs) zifite uruhare runini muguhuza no guha ingufu ibice bitandukanye. Guhuza imbaho ​​ebyiri za PCB nigikorwa gisanzwe, cyane cyane mugushushanya sisitemu igoye cyangwa kwagura imikorere. Muri iyi blog, tuzakuyobora muburyo bwo guhuza imbaho ​​ebyiri za PCB.

Intambwe ya 1: Menya ibisabwa guhuza:
Mbere yo kwibira mubikorwa, ni ngombwa kumenya ibikenewe byihariye byo guhuza imbaho ​​ebyiri za PCB. Irashobora gukoreshwa mu kwagura imikorere, gukora imirongo minini, cyangwa koroshya itumanaho hagati yimbaho ​​ebyiri. Uku gusobanukirwa kuzatuyobora muguhitamo uburyo bukwiye bwo guhuza.

Intambwe ya 2: Hitamo uburyo bwo guhuza:
Hariho uburyo bwinshi bwo guhuza imbaho ​​ebyiri za PCB. Reka dusuzume amahitamo amwe:

1. Gusudira:
Kugurisha nuburyo bukoreshwa cyane bwo kwinjiza imbaho ​​za PCB. Harimo gutanga amashanyarazi mugushonga icyuma (kugurisha) kugirango habeho umurunga ukomeye hagati yumuringa wumuringa wibibaho bibiri. Witondere kubihuza neza kandi ukoreshe icyuma kigurisha ubushyuhe bukwiye kubicuruzwa byizewe.

2. Umuhuza:
Gukoresha umuhuza bitanga uburyo bworoshye bwo guhuza no guhagarika imbaho ​​za PCB. Hariho ubwoko butandukanye bwihuza kumasoko nkimitwe, socket hamwe ninsinga. Hitamo ubwoko bwihuza ukurikije ibyo usabwa byihariye.

3. Wiring:
Kubintu byoroshye kandi byigihe gito, insinga zirashobora gukoreshwa muguhuza ibikenewe hagati yimbaho ​​za PCB. Kuramo insinga, uyihambire hamwe nuwagurishije, hanyuma ubihuze nudupapuro twabo ku mbaho ​​zombi. Ubu buryo ni ingirakamaro mugihe cya prototyping cyangwa ikosora.

Intambwe ya 3: Tegura ikibaho cya PCB:
Mbere yo gukomeza guhuza, menya neza ko imbaho ​​zombi za PCB ziteguye kwishyira hamwe:

1. Sukura hejuru: Koresha inzoga ya detergent cyangwa isopropyl kugirango ukureho umwanda wose, ibisigara bya flux cyangwa oxyde mumashanyarazi.

2. Hindura neza imiterere yibigize: Niba ushaka guhuza imbaho ​​za PCB ziteranijwe, nyamuneka urebe neza ko ibice biri ku mbaho ​​zombi bitazabangamirana. Hindura imiterere nibiba ngombwa.

Intambwe ya 4: Shyira mubikorwa uburyo bwo guhuza:
Noneho ko dufite uburyo bwo guhuza hamwe nubuyobozi bwa PCB twiteguye, reka dutangire kubahuza:

1. Uburyo bwo gusudira:
a. Huza ikibaho cya PCB neza, urebe neza ko amakariso y'umuringa ahuye nayo.
b. Koresha akantu gato ka flux kuri padi kugirango ukureho okiside no kwanduza.
c. Shyushya icyuma hanyuma ukore ku gihuru cyagurishijwe kugirango umugurisha ushongeshe atemba neza hagati yipaki. Witondere kudashyushya ibice kuri PCB.

2. Uburyo bwo guhuza:
a. Hitamo umuhuza ukwiye kubuyobozi bwawe hanyuma ubishyire ukurikije PCB ebyiri.
b. Wemeze guhuza neza kandi usunike abahuza hamwe kugeza igihe bahujwe neza.

3. Uburyo bwo gukoresha insinga:
a. Menya isano isabwa hagati yimbaho ​​ebyiri za PCB.
b. Kata uburebure bukwiye bw'insinga hanyuma wambure impera.
c. Gufata impera zinsinga hamwe nugurisha bizamura ihuza ryizewe.
d. Kugurisha insinga zometseho zirangirira kuri padi ihuye kuri PCBs zombi, kugirango uhuze neza.

Guhuza imbaho ​​ebyiri za PCB nubuhanga bwingenzi kubakunzi ba electronics hamwe nababigize umwuga. Ukurikije intambwe ku ntambwe ubuyobozi bwatanzwe hejuru kandi uzi ibisabwa byihariye, urashobora gukora neza ihuza ryizewe hagati yubuyobozi bwa PCB. Gusa wibuke kwitonda muriki gikorwa kugirango utangiza ikibaho cyangwa ibice. Guhuza neza!
