Daweyntii Daaweynta Foolka naxaas ee duuban

Foolo naxaas ahWaa shey muhiim u ah warshadaha wareegga elektiroonigga ah, iyo dusha sare iyo nadaafaddooda gudaha ayaa si toos ah u go'aamiya kalsoonida habraacyada hoos udhaca sida daboolka iyo kuleylka. Maqaalkani wuxuu falanqeeyaa farsamada kaas oo daweynta lagu xuseynayo ay u fiican tahay waxqabadka fashinka naxaasta naxaas ah ka soo qaadashada iyo aragtiyada arji. Adeegsiga xogta dhabta ah, waxay muujineysaa laqabsashada xaaladaha ay ku hayaan heerkulka heerkulka heerkulka. Birta ka timaadda saamiga sicirka qotodheer ee hantida leh ee ku dhex jira dhalooyinka warshadaha, oo siiya xalka xalka-sare ee xalka loo yaqaan 'copper' ee wax soo saarka elektiroonigga ah.

1. Xudunta geedi socodka sharaf-darrooyinka: Dual ka saarista dusha sare iyo dufanka gudaha

1.1 Arimaha saliida haraaga ah ee geedi socodka

Intii lagu gudajiray soo saarista foil cabitaan naxaas ah, guntin naxaas ah ayaa maray tillaabooyin badan oo duudduuban si loo sameeyo qalab foil. Si loo yareeyo kuleylka deloral iyo xijaabta, saliidaha (sida saliidaha macdanta iyo saliidaha isku-darka) waxaa loo isticmaalaa inta udhaxeysa liiska iyoFoil naxaas ahdusha sare. Si kastaba ha noqotee, hanaankani wuxuu horseedaa in lagu keydiyo dulucda iyada oo loo marayo laba dariiq oo aasaasi ah:

• ADSOORKA DARKA: Kaar ka hooseysa cadaadiska, filimka saliida ee yar yar (0.1-0.5μm dhumucdu) waxay ku dhejisaa dusha sare ee naxaas ah.
• Gudaha gudaha: Inta lagu gudajiro caqabadaha digaaga, jilicsanaanta naxaasta ah ayaa soo saarta cilladaha microscopic (sida jahwareerka iyo hubka), si loo dhigo silsilado molecules (C12-C18) si ay u galaan fash-ka-dhexaadka, oo ay gaaraan qoto dheer oo ah 1-3μm.

1.2 Xaddidnaanta hababka nadiifinta dhaqameed

Hababka nadiifinta dusha sare ee dusha sare (tus.70-85%, laakiin aan waxtar lahayn ka dhanka ah dufanka gudaha ee gudaha ah. Xogta tijaabada ayaa muujinaya in aan lahayn nabaad-guurka qoto dheer, dufan gudaha ah dib-u-soo-muuqan dusha sare ka dib30 daqiiqo 150 ° C, heerka dib-u-dejinta ee0.8-1.2G / M², sababaya "faddaraynta labaad."

1.3 Wax ka qabashada farsamada guud ee nabaad-guurka

Birta ka imanaysa birtaSoosaarka kiimikada + firfircoonaanta ultrasonic "Hawsha Isku-dhafan:

1. Soo saarista kiimikada: Wakiilka caadada ee caadada ah (ph 9.5-10.5) Wuxuu burburin karaa moleekul dheer oo silsilad ah, sameynta dhismayaasha biyaha-milmi-ku-dhigga.
2. Caawinta Ultrasonic: 40khz hytrasound-ka-sare wuxuu abuuraa saameynta cavitation-ka, jebinta xoogga xadka ee u dhexeeya dufanka gudaha ah iyo naaska naxaasta, kor u qaadista hufnaanta kala-baxa.
3. Qalajinta faaruq: Furuur deg deg ah ee -0.08MPA cadaadiska taban ayaa ka hortagaya oksidation.

Hawshani waxay yareysaa hadhaaga dufanka≤5MG / M²(La kulanka IPC-4562 heerarka ≤15mg / m²), gaarista> 99% hufnaanta ka saaridaloogu talagalay dufanka gudaha ee gudaha ah.

2. Saamaynta tooska ah ee daaweynta sharaf-darrada ee ku saabsan daboolka iyo hanaannada kuleylka kuleylka

2.1 Ku-xoojinta adhesion ee Codsiyada Darajooyinka

Qalabka daboolanFoil naxaas ah. Dufanka hadhaaga haraaga ah waxay keenaysaa arrimaha soo socda:

• Hoos udhaca tamarta galmada: Hydrophobisty of dufanku waxay kordhisaa xagal xiriirka ee xalka dahaarka ka soo baxa15 ° ilaa 45 °, caqabad ku noqoshada qoynta.
• Xaraashka xirmada kiimikada: Lakabka dufanku wuxuu kudhacayaa kooxaha hyroxyl (-h) ee dusha naxaasta ah, ka hortagga falcelinta kooxaha firfircoon ee resin.

Isbarbardhiga waxqabadka ee dhameystiran Vs. Foil ceper oo joogto ah:

2.2 Lahnaanta la xoojiyay ee lagu xakameynayo

Inta lagu guda jiro ganta-heerkulka-sare (180-220 ° C), dufanka haraaga ah ee fashilka naxaaska ah ee joogtada ahi waxay horseedaa guuldarro badan:

• Qaab dhismeedka xumbada: Dufanka uumiga ayaa abuuraya10-50μM oo xumbo ah(cufnaanta> 50 / cm²).
• Is dhexgalka: Grease reduces van der Waals forces between epoxy resin and copper foil, decreasing peel strength by30-40%.
• Khasaaraha Dielection: Dufan bilaash ah waxay keentaa isbeddelada joogtada ah ee Dielectric (DK Venrices> 0.2).

Ka bacdi1000 saacadood oo ah 85 ° C / 85% RHGING, BirtaFoil naxaas ahBandhigyada:

• Cufnaanta xumbada: <5 / cm² (celcelis ahaan warshadaha> 30 / cm²).
• Xoogga diirka: Ilaalinta1.6n / cm(qiimaha bilowga ah1.8n / cm, heerka sharafta oo keliya 11%).
• Xasilinimada Dielectric: Vardijin dk ≤0.05, kulan5g milimitir-rughtremic-ka si isdaba joog ah.

3. Xaaladda warshadaha iyo booska hoose ee xuska

3.1 Caqabadaha Warshadaha: Isu-duwaha Qaab-dhismeedka Qiimaha

Kor90% ee soosaarayaasha xoqida naxaas ahFududeeynta ka shaqeynta si aad u dhinto kharashaadka, ka dib shaqo-qabad aasaasi ah:

Duulista

Qaabkan kaliya wuxuu ka saaraa dufanka dusha sare, oo leh isbadalada dib-u-dhigga dusha sare ee dhajinta± 15%(Nidaamka birta ka sareeya ayaa ku sugan gudaha± 3%).

3.2 CARRUURTA CARUURTA "ZERE-ka-cillad" nidaamka tayada tayada leh

• Korjoogteynta khadka tooska ah: Fallar Fluorescescence (XRF) ee loo adeegsado waqtiga-dhabta ah ee waxyaabaha ku saabsan walxaha hadhaaga ah (s, cl, iwm.).
• Dardargelinta Dayactirka gabowga: Naxdin daran200 ° C / 24hShuruudo lagu hubinayo dib-u-soo-nooleynta eber.
• Traceact-Garsooyin buuxa: Liibaan kasta waxaa ku jira isku xirka QR32 Qiyaasta Geediniinta Muhiimka ah(tus., heerkulka sharaf-darrooyinka, awoodda ultrasonic).

4. Gunaanad: Daweyntii Daaweynta - aasaaska soosaarka elektiroonigga ee dhamaadka

Daaweynta qoto dheer ee fashilka xoqida ee duuban ma aha oo keliya nidaamka casriyeynta laakiin la qabsiga fikirka hore ee codsiyada mustaqbalka. Tikniyoolajiyadda hore ee birta ee tikniyoolajiyadda waxay kor u qaadaan naxaas sifee nadaafadda heerka atomikada, bixintaXaqiijinta Heerkaloogu tala-galayXiriirkii Censil-ka Sare (HDI), Wareegga Gawaarida dabacsaniyo meelaha kale ee dhamaadka-sare.
