Nibihe bikoresho bikunze gukoreshwa kuri prototypes ya PCB?

Ku bijyanye na prototyping ya PCB, guhitamo ibikoresho byiza ni ngombwa. Ibikoresho bikoreshwa muri prototypes ya PCB birashobora kugira ingaruka zikomeye kumikorere, kwizerwa, no kuramba kwibicuruzwa byanyuma.Muri iyi nyandiko ya blog, tuzareba bimwe mubikoresho bikoreshwa cyane mubuyobozi bwa PCB prototyping hanyuma tuganire kubyiza nibibi.

1.FR4:

FR4 kugeza ubu ni ibikoresho bikoreshwa cyane kuri PCB ya prototyping. Nibirahuri bishimangira epoxy laminate izwiho kuba ifite amashanyarazi meza cyane. FR4 nayo ifite ubushyuhe bwinshi, bigatuma ikoreshwa mubisabwa bisaba ubushyuhe bwo hejuru.

Kimwe mu byiza byingenzi bya FR4 nigiciro-cyiza. Birahendutse ugereranije nibindi bikoresho ku isoko. Byongeye kandi, FR4 ifite imashini ihamye kandi irashobora kwihanganira imihangayiko yo hejuru idahindagurika cyangwa ngo ivunike.

Ariko, FR4 ifite aho igarukira. Ntabwo ikwiranye na porogaramu zisaba imikorere yumurongo mwinshi kubera ko ugereranije na dielectric ihoraho. Byongeye kandi, FR4 ntabwo ikwiranye na porogaramu zisaba igihombo gito cyangwa kugenzura inzitizi zikomeye.

2. Rogers:

Rogers Corporation nubundi buryo bukunzwe kubuyobozi bwa PCB prototyping. Ibikoresho bya Rogers bizwiho gukora cyane, bituma bikenerwa muburyo butandukanye, harimo icyogajuru, itumanaho n’inganda zitwara ibinyabiziga.

Ibikoresho bya Rogers bifite ibikoresho byiza byamashanyarazi, harimo gutakaza dielectric nkeya, kugoreka ibimenyetso bike no gutwara ubushyuhe bwinshi. Bafite kandi umutekano muke kandi barashobora kwihanganira ibidukikije bibi.

Nyamara, ingaruka nyamukuru yibikoresho bya Rogers nigiciro cyinshi. Ibikoresho bya Rogers bihenze cyane kuruta FR4, birashobora kuba imbogamizi kumishinga imwe n'imwe.

3. Ibyuma byingenzi:

Ibyuma Core PCB (MCPCB) nubwoko bwihariye bwa prototype ya PCB ikoresha intoki yicyuma aho gukoresha epoxy cyangwa FR4 nka substrate. Icyuma cyicyuma gitanga ubushyuhe bwiza cyane, bigatuma MCPCB ikwiranye nibisabwa bisaba LED zifite ingufu nyinshi cyangwa ibikoresho bya elegitoroniki.

MCPCB isanzwe ikoreshwa munganda zimurika, inganda zimodoka ninganda za electronics. Batanga imicungire myiza yubushyuhe ugereranije na PCBs gakondo, bityo bikongerera ubwizerwe muri rusange no kuramba kwibicuruzwa.

Ariko, MCPCB ifite ibibi bimwe. Birahenze kuruta PCB gakondo, kandi ibyuma byibyuma biragoye gukora imashini mugihe cyo gukora. Byongeye kandi, MCPCB ifite imiterere ihindagurika kandi ntabwo ikwiriye kubisabwa bisaba kunama cyangwa kugoreka.

Usibye ibikoresho byavuzwe haruguru, hari nibindi bikoresho byihariye biboneka kubisabwa byihariye. Kurugero, byoroshye PCB ikoresha polyimide cyangwa polyester firime nkibikoresho fatizo, byemerera PCB kunama cyangwa guhindagurika. Ceramic PCB ikoresha ibikoresho byubutaka nka substrate, ifite ubushyuhe bwiza bwumuriro nubushobozi bwihuse.

Muri make, guhitamo ibikoresho bikwiye kuri prototype yubuyobozi bwa PCB nibyingenzi kugirango ugere kubikorwa byiza, kwiringirwa, no kuramba. FR4, Rogers, hamwe nibikoresho byibanze nibikoresho bimwe mubisanzwe, buri kimwe gifite ibyiza n'ibibi. Reba ibisabwa byihariye byumushinga wawe kandi ubaze inama yumwuga wa PCB wabigize umwuga kugirango umenye ibikoresho byiza bya prototype yawe ya PCB.
