Iimfihlo ze-Flex PCB Stack-Up: Izakhiwo ezi-single ukuya kwezi-4 ezichongiweyo (Isikhokelo se-PI/PET)
Ukuqonda ilungelo Ukufakwa kwe-Flex PCB kubalulekile ekulinganiseni ukusebenza, iindleko kunye nokuthembeka. Esi sikhokelo sityhila indlela yokukhetha eyona ifanelekileyo ulwakhiwo lwemaleko, izintokunye imithetho yoyilo kwiisekethe eziguquguqukayo kuzo zonke iimboni kuquka iimoto, ezonyango, izixhobo ze-elektroniki zabathengi, kunye nezixhobo ezinxitywayo.
I. I-PCB yeFlex enoMaleko omnye: Ukusebenza okuqhutywa bubukhulu
| Uhlobo | I-substrate | Ubukhulu | Inzuzo ephambili | Eyona ndlela ilungileyo yokusebenzisa | Umngcipheko Wokungaphumeleli Ngaphandle |
|---|---|---|---|---|---|
| I-Standard Single | I-PI | 25μm | Ixabiso eliphantsi | Iifowuni eziphathwayo, iiTablets | Iinyembezi ezigobileyo |
| Ityebile kakhulu | I-PI | 50μm | >2X Ukumelana Neenyembezi | Iziqhagamsheli zeShishini | Akukho (Ukuqina okuphuculweyo) |
| Ecacileyo | I-PET | 36μm | >85% Ukuhanjiswa kokukhanya | Imicu ye-LED, iiDisplays | Ukubola kwe-UV |
Ingcebiso yoNjineli: I-PET 36μm ixabisa ngaphantsi kwe-30% kune-PI kodwa yonakala ngaphezu kwe-105°C. Soloko uqinisekisa iinkcukacha zobushushu ngaphambi kokukhetha.
II. I-PCB eFlex eneMaleko Ambini: Ukulinganisela iiNtambo kunye nokuqina
| Uhlobo | Umthetho Woyilo Olubalulekileyo | Ingcebiso yeCopper |
|---|---|---|
| I-2L esemgangathweni | I-Coverlay ikhethwayo kwizicelo ezingashukumiyo | I-ED Copper (Ukugxila kwiindleko) |
| I-2L Etyebileyo Kakhulu | Isigqubuthelo esiyimfuneko solawulo lwe-impedance | I-RA Copper (≥100K flex) |
| I-2L ecacileyo | Ziphephe iimaski ezisongelwayo; sebenzisa izincamathelisi ezicacileyo | Ubhedu oluqengqelekayo |
Into yokuphonononga: Isixhobo esinxitywayo i-OEM sinciphise umahluko we-impedance nge-62% kusetyenziswa isakhiwo se-PI 50μm + coverlay.
III. Ii-PCB ezi-4 eziguquguqukayo kunye nee-Multi-Layer Flex
1. Inkxaso yoBungqingqwa beCopper
-
·Iileya zangaphakathi: 1/3oz (18μm), 0.5oz (35μm), 1oz (70μm)
-
·Iileya zangaphandle: Kufana nalapha ngasentla, kunye nokugqitywa kwe-ENIG okanye i-Immersion Tin okukhethwayo
2. Izakhiwo zeLamination
| Uhlobo lweStack | Uphawu lwesazisi | Ngaba iCoverlay isetyenzisiwe? | Ityala Eliqhelekileyo Lokusetyenziswa |
|---|---|---|---|
| I-4L esemgangathweni | – | Hayi | Uyilo lwabathengi olunoxabiso oluphantsi |
| I-4L ethembekileyo kakhulu | R | Ewe | Iimoto kunye nenqanaba lezonyango |
Kubalulekile: Kwi-1oz yobhedu lwangaphakathi, i-coverlay iyimfuneko ukuze ihlangabezane nemigangatho ye-IPC-2223. Ukusilela ukuyifaka kudla ngokukhokelela ekuqhekekeni.
3. Ii-Stack-Ups ezenziwe ngokwezifiso
-
·Uqwalaselo oluxhaswayo: Ii-stacks ze-PI/PET hybrid ezinamalaya ama-6 eziqinileyo neziguquguqukayo
-
·Irediyasi eNcinci yokugoba: Ubukhulu bebhodi iyonke yi-6 × (umz., 0.3mm kwizakhiwo ze-4L)
IV. Ukukhethwa kwezinto: Iimpawu zoKusebenza koMgangatho
| Izinto eziphathekayo | Uphawu oluPhambili | Inzuzo ephambili | Ixabiso nge-m² nganye | Umda woBushushu |
|---|---|---|---|---|
| I-PI 25μm | IDuPont Pyralux | Ukuthembeka okusemgangathweni wegolide | $18 | 200°C |
| I-PI 50μm | iTamida | Ukungalingani okuphantsi kwe-CTE | $24 | 240°C |
| I-PET 36μm | IMitsubishi | Ukumelana ne-UV, ukonga iindleko | $11 | 105°C |
Iziphumo zovavanyo: I-Taimide PI 50μm iphila imijikelo eguquguqukayo engama-200,000, idlula kakhulu umndilili woshishino wemijikelo engama-50,000.
V. Ziphephe Iimpazamo Ezibizayo: Imithetho Ebalulekileyo Yoyilo
1. Izicelo zokugoba eziDynamic
-
