Sirta Isugeynta PCB-ga ee Flex-Up: Qaab-dhismeedyo Hal ilaa 4-Lakab ah oo La Fasiray (Tilmaamaha PI/PET)
Fahmidda xuquuqda Isugeynta PCB-ga dabacsan waa mid muhiim u ah dheellitirka waxqabadka, kharashka, iyo isku halaynta. Tilmaamahan wuxuu muujinayaa sida loo doorto midka ugu wanaagsan qaab-dhismeedka lakabka, agab, iyo xeerarka naqshadeynta wareegyada dabacsan ee warshadaha oo dhan oo ay ku jiraan baabuurta, caafimaadka, elektaroonigga macaamiisha, iyo aaladaha la xiran karo.
I. PCB-ga Lakabyada Hal-Lakab leh: Waxqabadka Dhumucda ku salaysan
| Nooca | Substrate | Dhumucda | Faa'iidada Muhiimka ah | Kiiska Isticmaalka ugu Fiican | Khatarta Guuldareysiga La'aanteed |
|---|---|---|---|---|---|
| Hal-hal ah oo Caadi ah | PI | 25μm | Qiimaha ugu hooseeya | Taleefannada casriga ah, Kiniiniyada | Ilmo ku jira qaloocyada firfircoon |
| Aad u qaro weyn | PI | 50μm | > 2X Iska caabinta Ilmada | Xidhiidhiyayaasha Warshadaha | Lama Helin (Awood-siin la xoojiyay) |
| Hufnaan | XAYWAANKA CAAFIMAADKA | 36μm | >85% Gudbinta Iftiinka | Xariijimaha LED-ka, Bandhigyada | Qasabka UV |
Talo Injineer: PET 36μm wuxuu ku kacayaa ~30% ka yar PI laakiin wuxuu hoos u dhacaa heerkul ka sarreeya 105°C. Had iyo jeer hubi tilmaamaha kulaylka ka hor intaadan dooran.
II. PCB-ga Laba-Lakab leh ee Dabacsan: Dheelitirka Fiilooyinka & Waarta
| Nooca | Xeerka Naqshadeynta Muhiimka ah | Talo soo jeedinta naxaasta |
|---|---|---|
| Heerka 2L | Coverlay ikhtiyaari ah oo loogu talagalay codsiyada taagan | ED Copper (Diiradda Kharashka) |
| 2L oo aad u qaro weyn | Daboolidda qasabka ah ee xakamaynta iska caabinta | Naxaasta RA (≥100K dabacsan) |
| 2L oo hufan | Ka fogow maaskaro alxan ah; isticmaal dhejis hufan | Naxaas Duuban oo Duuban |
Daraasad Kiis: Qalab la xiran karo oo OEM ah ayaa hoos u dhigay kala duwanaanshaha impedance 62% iyadoo la isticmaalayo qaab-dhismeedka PI 50μm + daboolka.
III. PCB-yada dabacsan ee 4-Lakab iyo kuwa lakabka badan leh
1. Taageerada Dhumucda Naxaasta
-
·Lakabyada Gudaha: 1/3oz (18μm), 0.5oz (35μm), 1oz (70μm)
-
·Lakabyada Dibadda: Sida kor ku xusan, oo leh ikhtiyaari ENIG ama dhammaystirka Tin Immersion ah
2. Qaab-dhismeedka Lamination-ka
| Nooca Istuudka | Astaanta Aqoonsiga | Daboolida ma la isticmaalay? | Kiiska Isticmaalka Caadiga ah |
|---|---|---|---|
| Heerka 4L | - | Maya | Naqshadaha macaamiisha ee xasaasiga ah |
| Kalsooni Sare 4L | R | Haa | Gaadiidka iyo heerka caafimaadka |
Muhiim ah: Naxaasta gudaha ee 1oz, daboolku waa qasab si loo buuxiyo heerarka IPC-2223. Ku guuldareysiga in lagu daro badanaa waxay horseedaa kala-goyn.
3. Ururinta Gaarka ah ee Gaarka ah
-
·Qaabeynta la Taageero: 6-lakab oo adag oo dabacsan, PI/PET isku-dhafan oo is-dhexgal ah
-
·Radius-ka Laabista Ugu Yar: 6 × dhumucda looxa guud (tusaale ahaan, 0.3mm dhismaha 4L)
IV. Xulashada Agabka: Tijaabooyinka Waxqabadka Summada
| Alaab | Nooca ugu Sareeya | Faa'iidada Muhiimka ah | Qiimaha halkii m² | Xadka Heerkulka |
|---|---|---|---|---|
| PI 25μm | DuPont Pyralux | Isku halaynta heerka dahabka | $18 | 200°C |
| PI 50μm | Tamida | Isbarbardhig la'aanta CTE ee hooseysa | $24 | 240°C |
| PET 36μm | Mitsubishi | Iska caabbinta UV, kharashka badbaadinta | $11 | 105°C |
Natiijada Imtixaanka: Taimide PI 50μm waxay ka badbaado 200,000 wareeg oo dabacsan, taasoo si weyn uga badan celceliska warshadaha ee 50,000 wareeg.
V. Ka fogow Khaladaadka Khaaska ah: Xeerarka Naqshadeynta ee Muhiimka ah
1. Codsiyada Laabista Firfircoon
-
·Loo baahan yahay: RA Copper + PI ≥25μm; ka fogow aagagga adag meelaha firfircoon
-
·Ka fogowED Naxaasta ku jirta aagagga dabacsan - waxay u nugul tahay inay dillaacdo marka loo eego 5,000 wareeg
2. Naqshadaha Soo Noqnoqda Sare
-
·Isticmaal Rogers RO3000 taxane leh FCCL-ka aan xabag lahayn
