Bambanci tsakanin birgima na jan karfe (RA copper foil) da foil na tagulla na electrolytic (ED copper foil)

Rufin tagullaabu ne da ya zama dole a masana'antar allon kewayawa saboda yana da ayyuka da yawa kamar haɗin kai, haɓakawa, watsar da zafi, da garkuwar lantarki. Muhimmancinsa a bayyane yake. A yau zan yi muku bayaninbirgima tagulla(RA) da Bambancin dake tsakaninelectrolytic jan karfe foil(ED) da kuma rarrabuwa na PCB tagulla foil.

 

PCB tagulla foilabu ne mai sarrafa kayan aiki da ake amfani da shi don haɗa kayan aikin lantarki akan allunan kewayawa. Dangane da tsarin masana'antu da aikin, PCB foil jan karfe za a iya kasu kashi biyu: birgima na jan karfe (RA) da foil na tagulla (ED).

An yi birgima da foil ɗin tagulla da tsantsa na jan ƙarfe ta hanyar ci gaba da birgima da matsawa. Yana da ƙasa mai santsi, ƙarancin ƙazanta da ingantaccen ƙarfin lantarki, kuma ya dace da watsa sigina mai tsayi. Koyaya, farashin birgima na tagulla ya fi girma kuma kauri yana iyakance, yawanci tsakanin 9-105 µm.

 

Ana samun foil ɗin jan ƙarfe na lantarki ta hanyar sarrafa jigo na electrolytic akan farantin tagulla. Gefe guda yana da santsi, gefe guda kuma maras kyau. The m gefen yana bonded da substrate, yayin da m gefen da ake amfani da electroplating ko etching. Abubuwan da ke tattare da foil na tagulla na electrolytic shine ƙananan farashinsa da kewayon kauri, yawanci tsakanin 5-400 µm. Duk da haka, yanayin yanayinsa yana da girma kuma ƙarfin wutar lantarki ba shi da kyau, wanda ya sa ba ya dace da watsa sigina mai girma.

Rarrabewa na PCB foil tagulla

 

Bugu da kari, bisa ga roughness na electrolytic jan karfe foil, shi za a iya kara zuwa kashi kamar haka:

 

HTE(High Zazzabi elongation): Babban zafin jiki elongation jan karfe tsare, yafi amfani a Multi-Layer kewaye allon, yana da kyau high-zazzabi ductility da bonding ƙarfi, da roughness ne kullum tsakanin 4-8 µm.

 

RTF(Reverse Treat Foil): Juya bi da foil tagulla, ta ƙara takamaiman abin rufe fuska na guduro a gefen santsi na foil ɗin jan ƙarfe na electrolytic don haɓaka aikin mannewa da rage rashin ƙarfi. Matsakaicin girman shine yawanci tsakanin 2-4 µm.

 

ULP(Ultra Low Profile): Tsararren bayanin martaba na jan ƙarfe, wanda aka ƙera ta amfani da tsari na musamman na electrolytic, yana da ƙarancin ƙarancin ƙasa kuma ya dace da watsa sigina mai sauri. Matsakaicin girman shine yawanci tsakanin 1-2 µm.

 

HVLP(Maɗaukakin Maɗaukakin Ƙarfin Maɗaukaki): Tsararren ƙarfe mai ƙarfi mai ƙarfi. Dangane da ULP, ana kera shi ta hanyar haɓaka saurin electrolysis. Yana da ƙananan ƙarancin ƙasa da ingantaccen samarwa. Tsawon daji shine 0.5-1 µm. .
