Nigute Rogers Pcb yahimbwe?

Rogers PCB, izwi kandi ku izina rya Rogers Printed Circuit Board, irazwi cyane kandi ikoreshwa mu nganda zitandukanye kubera imikorere yayo myiza kandi yizewe. Izi PCB zakozwe mubikoresho bidasanzwe byitwa Rogers laminate, bifite amashanyarazi yihariye nubukanishi. Muri iyi nyandiko ya blog, tuzibira muburyo bukomeye bwo gukora Rogers PCB, dushakisha inzira, ibikoresho, nibitekerezo birimo.

Kugira ngo twumve inzira ya Rogers PCB yo gukora, tugomba mbere na mbere gusobanukirwa icyo kibaho icyo aricyo kandi tugasobanukirwa icyo Rogers laminates isobanura.PCBs nibice byingenzi byibikoresho bya elegitoronike, bitanga ibikoresho byubufasha bwa mashini hamwe nu mashanyarazi. Rogers PCBs zishakishwa cyane mubisabwa bisaba kohereza ibimenyetso byihuta cyane, gutakaza bike no gutuza. Zikoreshwa cyane mu nganda nk'itumanaho, icyogajuru, ubuvuzi n'imodoka.

Rogers Corporation, ibikoresho bizwi cyane bitanga ibisubizo, yateje imbere Rogers laminates kugirango ikoreshwe mu gukora imbaho ​​zikora neza cyane. Rogers laminate ni ibintu byinshi bigizwe na ceramic yuzuyemo imyenda ya fiberglass yuzuye hamwe na hydrocarubone ya thermoset resin. Uru ruvange rugaragaza ibintu byiza byamashanyarazi nko gutakaza dielectric nkeya, ubushyuhe bwinshi bwumuriro hamwe nuburinganire buhebuje.

Noneho, reka twinjire mubikorwa bya Rogers PCB:

1. Igishushanyo mbonera:

Intambwe yambere mugukora PCB iyariyo yose, harimo na Rogers PCBs, ikubiyemo gushushanya imiterere yumuzunguruko. Ba injeniyeri bakoresha software yihariye kugirango bashushanye ibibaho byumuzunguruko, gushyira no guhuza ibice bikwiye. Icyiciro cyambere cyo gushushanya ningirakamaro muguhitamo imikorere, imikorere, nubwizerwe bwibicuruzwa byanyuma.

2. Guhitamo ibikoresho:

Igishushanyo kimaze kurangira, guhitamo ibikoresho biba ingirakamaro. Rogers PCB isaba guhitamo ibikoresho bikwiye bya laminate, hitabwa kubintu nkibisabwa bya dielectric bihoraho, ibintu bitandukana, ubushyuhe bwumuriro, hamwe nubukanishi. Rogers laminates iraboneka mubyiciro bitandukanye kugirango byuzuze ibisabwa bitandukanye.

3. Kata laminate:

Hamwe nigishushanyo hamwe nibikoresho byatoranijwe byuzuye, intambwe ikurikira nukugabanya Rogers laminate kubunini. Ibi birashobora kugerwaho ukoresheje ibikoresho byihariye byo gukata nkimashini za CNC, kwemeza ibipimo nyabyo no kwirinda ibyangiritse kubintu.

4. Gucukura no gusuka umuringa:

Kuri iki cyiciro, ibyobo byacukuwe muri laminate ukurikije igishushanyo mbonera. Ibyo byobo, byitwa vias, bitanga amashanyarazi hagati yinzego zitandukanye za PCB. Ibyobo byacukuwe noneho bikozwe mu muringa kugira ngo bigaragaze neza kandi bitezimbere uburinganire bwimiterere ya vias.

5. Kwerekana amashusho:

Nyuma yo gucukura, hashyizweho urwego rwumuringa kuri laminate kugirango habeho inzira ziyobora zisabwa kugirango PCB ikore. Ikibaho cyambaye umuringa cyometseho ibintu byoroshye urumuri rwitwa Photoresist. Igishushanyo cyumuzunguruko noneho cyimurirwa kumafoto ukoresheje tekinoroji yihariye nka Photolithography cyangwa amashusho ataziguye.

6. Gutera:

Igishushanyo mbonera cyumuzingo cyacapishijwe kumafoto, hakoreshwa imiti yimiti kugirango ikureho umuringa urenze. Etchant ishonga umuringa udakenewe, igasiga inyuma yumuzingi wifuzwa. Iyi nzira ningirakamaro mugushiraho inzira ziyobora zisabwa kugirango amashanyarazi ya PCB ahuze.

7. Guhuza ibice no kumurika:

Kubice byinshi Rogers PCBs, ibice byihariye bihujwe neza hakoreshejwe ibikoresho kabuhariwe. Izi nzego zegeranye kandi zomekwa hamwe kugirango zibe imiterere ihuriweho. Ubushyuhe n'umuvuduko bikoreshwa muburyo bw'amashanyarazi no guhuza ibice, byemeza ko bigenda neza.

8. Gukoresha amashanyarazi no kuvura hejuru:

Kurinda uruziga no kwemeza kwizerwa igihe kirekire, PCB ikora isahani hamwe nuburyo bwo kuvura hejuru. Icyuma cyoroshye (ubusanzwe zahabu cyangwa amabati) gishyizwe hejuru yumuringa ugaragara. Iyi coating irinda kwangirika kandi itanga ubuso bwiza bwo kugurisha ibice.

9. Maskeri ya Solder hamwe na ecran ya ecran:

Ubuso bwa PCB busizwe hamwe na mask yo kugurisha (ubusanzwe icyatsi), hasigara gusa aho bikenewe kugirango uhuze ibice. Uru rwego rwo kurinda rurinda ibimenyetso byumuringa ibintu bidukikije nkubushuhe, umukungugu, no guhura nimpanuka. Mubyongeyeho, ibice bya silkscreen birashobora kongerwaho kugirango bigaragaze imiterere yibigize, abashushanya ibyerekeranye nandi makuru afatika hejuru ya PCB.

10. Kwipimisha no kugenzura ubuziranenge:

Ibikorwa byo gukora bimaze kurangira, hakozwe gahunda yo kugerageza no kugenzura neza kugirango PCB ikore kandi yujuje ibyashizweho. Ibizamini bitandukanye nko kugerageza ubudahwema, gupima voltage nini no gupima impedance bigenzura ubunyangamugayo n'imikorere ya Rogers PCBs.

Muri make

Ibihimbano bya Rogers PCBs bikubiyemo uburyo bwitondewe burimo igishushanyo mbonera, imiterere, gutoranya ibikoresho, gukata laminate, gucukura no gusuka umuringa, amashusho yumuzunguruko, gutondeka, guhuza ibice no kumurika, gusasa, gutegura hejuru, mask yo kugurisha hamwe no gukoresha imashini zandika hamwe nibisobanuro byuzuye kwipimisha no kugenzura ubuziranenge. Gusobanukirwa nubuhanga bwinganda za Rogers PCB byerekana ubwitonzi, ubwitonzi, nubuhanga bugira uruhare mugukora izo mbaho ​​zikora neza.
