Amabanga yo gushyira hamwe PCB: Imiterere imwe kugeza kuri 4 yakuweho (Ubuyobozi bwa PI/PET)
Gusobanukirwa uburenganzira Gushyira hamwe PCB igendanye ni ingenzi cyane mu kuringaniza imikorere, ikiguzi, no kwizerwa. Iyi mfashanyigisho igaragaza uburyo bwo guhitamo uburyo bwiza bwo imiterere y'urwego, ibikoresho, na amategeko agenga igishushanyo mbonera ku nganda zikoresha imodoka, ubuvuzi, ibikoresho by'ikoranabuhanga bikoreshwa n'abantu, n'ibikoresho byambarwa.
I. PCB yoroshye ifite urwego rumwe: Imikorere ishingiye ku bunini
| Ubwoko | Inzu ntoya | Ubunini | Akamaro k'ingenzi | Isanduku nziza yo gukoresha | Ingaruka zo gutsindwa nta |
|---|---|---|---|---|---|
| Isanzwe imwe | PI | 25μm | Igiciro gito cyane | Telefoni zigendanwa, Tableti | Amarira ari mu miterere ihindagurika |
| Ubunini Bukabije | PI | 50μm | >2X Ubudahangarwa bw'amarira | Ibikoresho bihuza inganda | Ntacyo (Gukomera kurushaho) |
| Ibonerana | PET | 36μm | >85% Ihererekanya ry'urumuri | Imirongo ya LED, Ecran | Kwangirika kw'imirasire y'izuba |
Inama y'umuhanga: PET 36μm igura ~30% munsi ya PI ariko irangirika hejuru ya 105°C. Buri gihe genzura ibisabwa ku bushyuhe mbere yo guhitamo.
II. PCB ifite imiterere ibiri: Kunoza insinga no kuramba kwayo
| Ubwoko | Itegeko ry'ingenzi ry'igishushanyo mbonera | Inama ku mucunga |
|---|---|---|
| Isanzwe ya 2L | Gupfuka ubusa byifuzwa kuri porogaramu zidahinduka | Umuringa wa ED (Icyibandwaho ku Giciro) |
| 2L nini cyane | Igipfukisho cy'ingenzi cyo kugenzura impedance | Umuringa wa RA (≥100K flex) |
| Irabagirana 2L | Irinde udupfukamunwa two gusoda; koresha kole ibonerana | Umuringa uzungurutse |
Inyigo y'Urubanza: Igikoresho cyambarwa cya OEM cyagabanyije ihindagurika rya impedance ku kigero cya 62% hakoreshejwe imiterere ya PI 50μm + coverlay.
III. PCB zoroshye zifite imiterere 4 n'imiterere myinshi
1. Inkunga y'ubunini bw'umuringa
-
·Imbere mu byiciro: 1/3oz (18μm), 0.5oz (35μm), 1oz (70μm)
-
·Ibyiciro byo hanze: Kimwe n'ibyavuzwe haruguru, hamwe n'irangiza rya ENIG cyangwa Immersion Tin ry'ubushake
2. Imiterere y'ibice bitwikiriye
| Ubwoko bw'urutonde | Ikimenyetso cy'indangamuntu | Igipfukisho cyakoreshejwe? | Ikoreshwa Risanzwe |
|---|---|---|---|
| 4L isanzwe | – | Oya | Imiterere y'abaguzi ihendutse |
| Ifite ubushobozi bwo kwizerwa cyane 4L | R | Yego | Imodoka n'urwego rw'ubuvuzi |
Icy'ingenzi: Ku mucuzi w'imbere wa oz 1, gupfuka ni itegeko kugira ngo huzuzwe amabwiriza ya IPC-2223. Kutabishyiramo akenshi bituma habaho gutandukana.
3. Gushyira hamwe ibintu ku buryo bwihariye
-
·Imiterere ishyigikiwe: Imitako y'ibice 6 ihamye, PI/PET hybrid
-
·Umwanya muto wo kugonga: Ubugari bw'urubaho rwa 6 × (urugero, 0.3mm ku bikoresho bya 4L)
IV. Guhitamo ibikoresho: Ibipimo ngenderwaho by'imikorere y'ikirango
| Ibikoresho | Ikirango Gikomeye | Akamaro k'ingenzi | Igiciro kuri m² | Ubushyuhe ntarengwa |
|---|---|---|---|---|
| PI 25μm | DuPont Pyralux | Kwizerwa nk'uko bisanzwe muri zahabu | $18 | 200°C |
| PI 50μm | Tamida | Ubudasa buri hasi bwa CTE | $24 | 240°C |
| PET 36μm | Mitsubishi | Ubudahangarwa bw'imirasire ya UV, kugabanya ikiguzi | $11 | 105°C |
Ibisubizo by'ikizamini: Taimide PI 50μm igumana imikorere y’ingufu 200.000, irenga cyane impuzandengo y’inganda y’imikorere y’ingufu 50.000.
V. Irinde amakosa ahenze: Amategeko y'ingenzi agenga igishushanyo mbonera
1. Porogaramu zo gufunga zikoresha imbaraga
-
·Birasabwa: RA Umuringa + PI ≥25μm; irinde ahantu hakomeye hejuru y'ahantu hahinduka
-
·Irinde: ED Umuringa mu bice bihindagurika - ushobora kwangirika munsi y'amasaha 5.000
2. Ibishushanyo mbonera bikunze gukoreshwa cyane
-
·Koresha Rogers RO3000 urukurikirane hamwe na FCCL idafite kole
-
·Gukomeza Kwihanganira Dr muri ± 0.05 @ 10GHz kugira ngo RF yiringire
3. Kwizerwa kw'ibipimo by'imodoka n'ubuvuzi
-
Koresha indangamuntu "R" kuri stack-up IPC Class 3 ikurikiza amategeko
-
Menya neza CTE hagati y'ibice kugira ngo hirindwe ko ubushyuhe bunanirwa
Impamvu iyi nyandiko irusha izindi nyandiko zose z'amakuru
Isesengura ryacu rya Ibice 172 byakozwe na Flex PCB byananiwe yasanze ibyo 68% by'inenge byaturutse kuri:
-
1. Gukoresha ibyuma by'umuringa bya oz 1 nta gipfundikizo (delamination)
-
2. Gukoresha substrates za PET mu bice by'ubushyuhe (kwangirika kw'amazi mu kirere)
-
3. Gukoresha umuringa wa ED mu bice bihinduka (kunanirwa gucika intege mu gihe cy'umuruho)
Kuri IBYISHIMO BYOSE BYINSHI, turenga amahame ngenderwaho hamwe na:
-
·Ububiko bw'amakuru bwa ADN y'ibikoresho: Imirongo irenga 50.000 y'amakuru y'ibizamini ku mikoranire ya PI/PET
-
·Uruhererekane rw'Ibicuruzwa (AI): Iteganya ingaruka z'igihe cyo kwishyura Taiflex, DuPont, n'abandi
-
·Umugenzuzi w'Imari n'Igenamigambi: Amabendera ahura n'ibibazo mbere yo gukoresha ibikoresho cyangwa gukora
Suzuma byinshi ku gushushanya no gukora PCB ya Flex

- ·Ibintu Bijyanye n'Ibiciro bya PCB n'Ibiciro by'Ibiciro - Sobanukirwa ibintu bitwara amafaranga n'uburyo bwo kunoza ingengo y'imari yawe.
- ·Guhitamo ibikoresho bya PCB bihindagurika - Gusobanukirwa LCP, PI, ubwoko bw'imitako, n'udupira tw'umuringa.
- ·Flex PCB vs Rigid-Flex: Ni iyihe wahitamo? - Kugereranya tekiniki n'ikiguzi kugira ngo hafatwe ibyemezo byiza.
🌐 Amahame y'Umutungo wizewe n'Inganda
- ·Amahame ya IEEE ku gishushanyo mbonera cya PCB cyihuta cyane – Icyitonderwa cy'amabwiriza agenga ubuziranenge bw'ikimenyetso n'amabwiriza yo kubuza ikirere.
- ·IPC-6013 Isanzwe ku bijyanye n'imiyoboro y'amashanyarazi ihindagurika – Ibisabwa kugira ngo umuntu yemererwe gukoresha flex circuits.
- ·Ubushakashatsi ku Isoko rya Prismark - Iteganyagihe n'ubumenyi ku isoko ry'ibikoresho by'ikoranabuhanga bihindagurika.
