Niki fr4 pcb

FR4 ni ijambo rigaragara cyane iyo rigeze ku mbaho ​​zicapye (PCBs).Ariko mubyukuri PC4 ya PC4 ni iki?Kuki ikoreshwa cyane mubikorwa bya elegitoroniki?Muri iyi nyandiko ya blog, dufata umwete mwisi ya FR4 PCBs, tuganira kubiranga, inyungu, porogaramu n'impamvu aribwo buryo bwo guhitamo abakora ibikoresho bya elegitoroniki kwisi yose.

PCBs ya FR4 ni iki?

FR4 PCB bivuga ubwoko bwikibaho cyumuzingo cyacapwe cyakozwe ukoresheje flame retardant 4 (FR4) laminate.FR4 ni ibintu byinshi bikozwe mubirahuri bya fibre yibohesheje imyenda yatewe na flame retardant epoxy resin binder.Uku guhuza ibikoresho byemeza ko FR4 PCBs ifite amashanyarazi meza, kuramba no kurwanya umuriro.

Ibiranga FR4 PCB:

1. Gukwirakwiza amashanyarazi: FR4 PCB ifite ibikoresho byiza byo gukwirakwiza amashanyarazi.Ibikoresho bya fiberglass ikoreshwa muri laminate ya FR4 itanga imbaraga zo kumeneka cyane, ibimenyetso byizewe hamwe no gukwirakwiza ubushyuhe neza.

2. Imbaraga zumukanishi: FR4 laminates itanga imbaraga zumukanishi hamwe nuburinganire bwimiterere, bigatuma bikoreshwa mubikorwa bitandukanye.Barashobora kwihanganira ubushyuhe bwinshi, kunyeganyega no guhangayikishwa n’ibidukikije bitabangamiye imikorere.

3. Kubuza umuriro: Imwe mu miterere ikomeye ya FR4 PCB ni ukutagira umuriro.Epoxy yifata ikoreshwa muri laminate ya FR4 niyizimya, irinda ikwirakwizwa ryumuriro kandi ikanemeza umutekano wibikoresho bya elegitoroniki.

Ibyiza bya FR4 PCB:

1. Igiciro-Cyiza: FR4 PCB irahuzagurika kandi ihendutse, ugereranije nizindi substrate, irakoresha amafaranga menshi.Ibi bituma bahitamo bwa mbere kubikoresho byinshi bya elegitoroniki.

2. Guhinduranya: FR4 PCBs irashobora guhindurwa no gukorwa mubunini butandukanye, imiterere nuburyo butandukanye, bigatuma hashyirwaho ibishushanyo mbonera byumuzunguruko kandi byujuje ibisabwa bitandukanye.

3. Ibidukikije byangiza ibidukikije: FR4 PCB ntabwo irimo ibintu byangiza nka gurş cyangwa ibyuma biremereye, kubwibyo byangiza ibidukikije cyane.Bakurikiza amabwiriza ya RoHS (Kubuza Ibintu Byangiza) kandi bifatwa nkumutekano kubuzima bwabantu ndetse nibidukikije.

Ikoreshwa rya FR4 PCB:

FR4 PCBs zikoreshwa mubikorwa bitandukanye byinganda nibisabwa, harimo:

1. Ibyuma bya elegitoroniki byabaguzi: PC4s ya FR4 ikoreshwa cyane muri terefone zigendanwa, tableti, mudasobwa zigendanwa, televiziyo, imashini y’imikino n’ibindi bicuruzwa bya elegitoroniki, bigatuma ibikoresho bikora neza.

2. Ibikoresho byinganda: FR4 PCBs zikoreshwa mumashini yinganda, sisitemu yo kugenzura, gutanga amashanyarazi, hamwe nibikoresho byikora kubera imikorere yabyo kandi iramba.

3. Imodoka: FR4 PCBs ningirakamaro kuri electronics yimodoka, harimo sisitemu yo gucunga moteri, GPS yogukoresha, sisitemu ya infotainment, nibindi byinshi.Kurwanya urumuri no gukomera byemeza imikorere yizewe kandi yizewe mubidukikije bikaze byimodoka.

FR4 PCBs yahinduye inganda za elegitoronike hamwe n’imiterere yazo y’amashanyarazi n’ubukanishi, kutagira umuriro, no gukoresha neza ibiciro.Nkuko twabibonye, ​​guhinduka kwabo no kwizerwa bituma biba byiza kubikorwa bitandukanye.Akamaro kabo mubikoresho bya elegitoroniki, ibikoresho byinganda ninganda zitwara ibinyabiziga bigaragarira mubikorwa byabo bitagereranywa mugukora neza kandi neza ibikoresho bya elegitoroniki.Mugihe ikoranabuhanga rikomeje gutera imbere, PCBs za FR4 birashoboka ko zizakomeza kuba igice cyisi yisi ya none.
