Zvakavanzika zveFlex PCB Stack-Up: Zvivako zveSingle kusvika ku4-Layer Decoded (PI/PET Guide)
Kunzwisisa kodzero Kuunganidzwa kwePCB yakapfava Zvakakosha pakuenzanisa mashandiro, mutengo, uye kuvimbika. Gwaro iri rinoratidza masarudzo akakodzera chimiro cherukoko, zvinhuuye mitemo yekugadzira yematunhu anochinjika mumaindasitiri anosanganisira mota, zvekurapa, zvemagetsi zvevatengi, uye zvishandiso zvinopfekwa.
I. PCB yeFlex ine Rutivi Rumwe: Kushanda Kwayo Kunofambiswa Nehukobvu
| Rudzi | Substrate | Ukobvu | Chinhu Chinobatsira | Nyaya Yakanakisisa Yokushandisa | Njodzi Yekukundikana Pasina |
|---|---|---|---|---|---|
| Imwe Chete Yakajairika | PI | 25μm | Mutengo Wakaderera | Mafoni, Mapiritsi | Misodzi inokombama zvine simba |
| Gobvu Rakanyanya | PI | 50μm | >2X Kudzivirira Misodzi | Zvinobatanidza zveMaindasitiri | N/A (Kugara kwenguva refu kwakawedzerwa) |
| Kujeka | PET | 36μm | >85% Kutumira Chiedza | Zvidimbu zve LED, Zviratidzo | Kuora kweUV |
Zano reMainjiniya: PET 36μm inodhura ~30% pasi pePI asi inoderera pamusoro pe105°C. Gara uchiongorora zvinodiwa pakupisa usati wasarudza.
II. PCB yeDouble-Layer Flex: Kuenzanisa Wiring & Kugara kwenguva refu
| Rudzi | Mutemo weKugadzira Wakakomba | Zvinokurudzirwa nemhangura |
|---|---|---|
| Yakajairika 2L | Chifukidziro chinosarudzwa chekushandisa zvisina kusimba | ED Copper (Kutarisa Mutengo) |
| 2L Yakakora Zvakanyanya | Chifukidziro chinosungirwa chekudzora impedance | RA Copper (≥100K flex) |
| 2L yakajeka | Dzivisa mamasiki anonamira; shandisa manamatisi anoonekera | Mhangura Yakamonerwa |
Chidzidzo Chenyaya: Mudziyo unopfekwa weOEM wakaderedza musiyano weimpedance ne62% uchishandisa chimiro chePI 50μm + coverlay.
III. MaPCB ane 4-Layer uye Multi-Layer Flex
1. Rutsigiro rweKukora kweMhangura
-
·Zvikamu zvemukati: 1/3oz (18μm), 0.5oz (35μm), 1oz (70μm)
-
·Zvikamu zvekunze: Zvakafanana nezviri pamusoro apa, pamwe nesarudzo yeENIG kana Immersion Tin finish
2. Zvivako zveLamination
| Rudzi rweStack | Chiratidzo cheID | Chifukidziro Chinoshandiswa Here? | Nyaya Yekushandisa Yakajairika |
|---|---|---|---|
| Yakajairika 4L | – | Aihwa | Magadzirirwo evatengi anonyanya kudhura |
| Kuvimbika Kwakanyanya 4L | R | Ehe | Mota uye giredhi rekurapa |
Zvakakosha: Kune 1oz yemukati mhangura, chifukidziro chinodiwa kuti chisangane nezvinodiwa neIPC-2223. Kusaisa chifukidziro ichi kunowanzoita kuti pave nekubvisa dhayi.
3. Zvikamu Zvakagadzirwa Nemaoko
-
·Magadzirirwo Anotsigirwa: 6-layer rigid-flex, PI/PET hybrid stacks
-
·Nharaunda Yekukombama Isingasviki: 6 × ukobvu hwebhodhi rose (semuenzaniso, 0.3mm yekuvaka kwe4L)
IV. Kusarudzwa Kwezvinhu: Zviratidzo Zvekushanda Kwemhando
| Zvinhu | Brand Yepamusoro | Chinhu Chinobatsira | Mutengo pa m² | Muganho wekupisa |
|---|---|---|---|---|
| PI 25μm | DuPont Pyralux | Kuvimbika kwegoridhe | $18 | 200°C |
| PI 50μm | Tamida | Kusawirirana kweCTE kwakaderera | madhora makumi maviri nemana | 240°C |
| PET 36μm | Mitsubishi | Kudzivirira UV, kuchengetedza mari | madhora gumi nerimwe | 105°C |
Mhedzisiro yeMuedzo: Taimide PI 50μm inorarama 200,000 flex cycles, zvichipfuura zvakanyanya avhareji yeindasitiri ye50,000 cycles.
V. Dzivisa Zvikanganiso Zvinodhura: Mitemo Yekugadzira Yakakosha
1. Maitiro Ekushandisa Dynamic Bend
-
·Zvinodiwa: RA Copper + PI ≥25μm; dzivisa nzvimbo dzakaoma panzvimbo dzinoshanduka
-
·DzivisaED Copper munzvimbo dzinochinjika - inogona kutsemuka pasi pe5,000 cycles
2. Magadzirirwo Anowanzo shandiswa
-
·Shandisa Rogers RO3000 nhevedzano ine FCCL isina kunamira
-
·Chengetedza Kushivirira kwaDk mukati me ±0.05 @10GHz kuti RF ivimbike
3. Kuvimbika kweMotokari & Zvekurapa
-
Shandisa stack-up ID "R" ye Kutevedzera mitemo yeIPC Kirasi 3
-
Iva nechokwadi chekuti CTE pakati pezvikamu kudzivirira kutadza kushanda zvakanaka kwekupisa
Nei Gwaro Iri Richikunda Mapepa Eruzivo Akajairika
Ongororo yedu ye Mabheti ekugadzira eFlex PCB zana nemakumi manomwe nemaviri akakundikana akawana izvozvo 68% yezvikanganiso yakabva ku:
-
1. Kushandisa 1oz yemukati yemhangura isina chifukidziro (demination)
-
2. Kushandisa PET substrates munzvimbo dzinopisa (kukanganiswa kwemvura inoyerera)
-
3. Kushandisa mhangura yeED munzvimbo dzinoshanduka (kukundikana kuneta nekukurumidza)
Pa MUFARO AKAPFUMA WAKWANA, tinopfuura mwero ne:
-
·Dhatabhesi reDNA rezvinhu: Kupfuura zviuru makumi mashanu zve data rekuyedza pamisanganiswa yePI/PET
-
·Kutengesa Kugadzira AI: Inofanotaura njodzi dzenguva yekutungamirira kuTaiflex, DuPont, nevamwe
-
·Muongorori weStack-Up: Mireza inosawirirana pamberi pekushandisa maturusi kana kugadzirwa
Ongorora Zvakawanda nezve Flex PCB Design & Manufacturing

- ·Sarudzo yeZvinhu zveFlex PCB - Ruzivo pamusoro peLCP, PI, mhando dzezvinonamira, uye mafoil emhangura.
- ·Flex PCB vs Rigid-Flex: Ndeipi Yekusarudza? - Kuenzanisa kwehunyanzvi nemitengo kuti pave nesarudzo dziri nani.
🌐 Zviwanikwa Zvinovimbwa & Maitiro Eindasitiri
- ·Maitiro eIEEE ekugadzira PCB inomhanya zvakanyanya - Chirevo chekuvimbika kwechiratidzo uye nhungamiro dze impedance.
- ·IPC-6013 Standard yeMadunhu Anochinjika - Zvinodiwa zvekukodzera uye kugamuchirwa kwema flex circuits.
