Hand Soldering FPC Boards: Malebela a Bohlokoa le Mehopolo

Tsebisa

Ha ho bokelloa mapolanka a flexible printed circuit (FPC), ho soasoa ka letsoho ke mokhoa o sebelisoang haholo ka lebaka la ho nepahala le ho boloka chelete. Leha ho le joalo, ho na le lintlha tse 'maloa tsa bohlokoa tse lokelang ho nahanoa e le hore u finyelle khokahanyo e atlehileng ea solder.Ka poso ena ea blog, re tla tšohla lintlha tsa bohlokoa tse lokelang ho lefshoa ha liboto tsa potoloho tsa FPC li sebelisoa ka letsoho, ho kenyelletsa le mokhoa oa ho ikopanya pakeng tsa ntlha ea tšepe ea tšepe le karolo, mokhoa oa phepelo oa terata ea soldering, nako ea soldering le mocheso. li-setting, joalo-joalo E le tlhokomeliso ea bohlokoa ho netefatsa ts'ebetso e se nang sekoli ea welding. Ha re ikakhele ka setotsoana!

1. Mokhoa oa ho ikopanya pakeng tsa ntlha ea tšepe ea soldering le likarolo tse peli tse lokelang ho etsoa

Ho finyella kamano e matla pakeng tsa tšepe ea soldering le motsoako ke habohlokoa bakeng sa ts'ebetso e atlehileng ea soldering. Ka kopo ela hloko lintlha tse latelang:

I. Boloka ntlha ea tšepe ea solder e hloekile 'me e kentsoe ka makotikoti:Pele o qala ts'ebetso ea ho kopanya, etsa bonnete ba hore ntlha ea tšepe ea soldering e hloekile ebile e kentsoe ka makotikoti hantle. Sena se tiisa phetisetso e ntle ea mocheso le ho thibela oxidation, e bakang manonyeletso a boreleli a solder.

2. Kenya lehlakore le letona:boloka angle e loketseng pakeng tsa ntlha ea tšepe ea soldering le boto ea FPC. Ha e le hantle, angle e khothalletsoang e pakeng tsa 30 le 45 degrees. Sena se khothalletsa phetisetso e nepahetseng ea mocheso le ho thibela ho chesa haholo kapa likarolo tse senyang.

3. Kenya khatello e lekaneng:Kenya khatello e fokolang karolong e lokelang ho rekisoa, ha u ntse u etsa bonnete ba hore u se ke ua sebelisa matla a mangata haholo kaha sena se ka baka tšenyo. Sena se thusa ho netefatsa khokahanyo e nepahetseng le e tsitsitseng pakeng tsa ntlha ea tšepe ea soldering le boto ea FPC.

2. Mokhoa oa phepelo ea terata ea welding

Tsela eo terata ea welding e fanoang ka eona e phetha karolo ea bohlokoa ho fihlelleng khokahanyo e nepahetseng. Ka kopo latela litataiso tsena:

I. Sebelisa palo e nepahetseng ea solder:Qoba ho sebelisa solder e ngata haholo kaha e ka baka borokho kapa khutsufatso. Ka lehlakoreng le leng, solder e sa lekaneng e ka baka khokahanyo e fosahetseng. Ka hona, chelete e nepahetseng e tlameha ho sebelisoa ho latela boholo le ho rarahana ha motsoako oa solder.

2. Khetha terata ea boleng bo holimo ea solder:Kamehla sebelisa terata ea boleng bo holimo e loketseng ho cheseletsa boto ea potoloho ea FPC. Boleng ba terata ea solder bo ama haholo phello ea kakaretso ea solder.

3. Kenya terata ea welding ho tloha ka lehlakoreng le leng:Ho etsa bonnete ba hore mocheso o fetisa ka nepo, ka kopo kenya terata ea welding ho tloha ka lehlakoreng le leng la motsoako oa solder. Theknoloji ena e lumella solder ho phalla ka bolokolohi le ho theha maqhama a matla pakeng tsa likarolo.

3. Litlhophiso tsa nako le mocheso oa welding

Nako e nepahetseng ea soldering le litlhophiso tsa mocheso li bohlokoa ho finyella likhokahano tse ka tšeptjoang tsa soldering. Nahana ka lintlha tse latelang:

I. Fumana mocheso o nepahetseng:Itloaetse ka mefuta e khothalletsoang ea mocheso bakeng sa liboto tsa FPC tsa soldering. Ka kakaretso, mocheso o pakeng tsa 250 le 300 degrees Celsius o loketse. Leha ho le joalo, ho bohlokoa ho latela litataiso tse tobileng tse fanoeng ke moetsi ho thibela tšenyo ea likarolo tse bobebe.

2. Laola nako ea ho futhumatsa ka nepo:nako ea ho futhumatsa e ke ke ea e-ba khutšoanyane kapa e telele haholo. Ho futhumatsa nako e telele ho ka baka tšenyo ea karolo, ha mocheso o sa lekaneng o ka baka manonyeletso a fokolang a solder. Ikemisetse ho leka-lekanya hantle ka ho khomarela linako tse behiloeng tsa ho futhumatsa.

4. Litlhokomelo tsa ho cheselletsa

Ho qoba mathata a ka bang teng nakong ea ho cheselletsa, ho lokela ho nkoa mehato e hlokahalang. Kenyelletsa litataiso tse latelang:

I. Netefatsa moea o lekaneng:Sebetsa sebakeng se nang le moea o motle ho thibela ho phefumoloha lintho tse kotsi tse hlahisoang nakong ea ts'ebetso ea welding.

2. Kenya tšebetsong litemoso tsa ESD:Liboto tsa potoloho tsa FPC li ka hlaseloa ke electrostatic discharge (ESD). Sebelisa mete ea tšireletso ea ESD, marapo a letsoho le mehato e meng e nepahetseng ho qoba tšenyo e bakiloeng ke ESD.

3. Qoba ho chesa haholo:U se ke ua chesa haholo likarolo kapa libaka tse itseng nakong ea welding, ho seng joalo ho ka baka tšenyo. Boloka mokhoa o tsitsitseng le o laoloang ho thibela mathata a amanang le ho chesa haholo.

Ha re phethela

Ha o sebetsa le liboto tsa potoloho ea FPC, mekhoa e nepahetseng ea ho soasoa ka letsoho e bohlokoa ho netefatsa likhokahano tse tšepahalang le tse matla. Ka ho ela hloko ka hloko mekhoa ea ho ikopanya, lisebelisoa tsa terata, nako le maemo a mocheso, le ho latela mehato e hlokahalang ea ho itšireletsa, u ka fumana liphetho tse atlehileng tsa welding. Ka ho itloaetsa le ho ela hloko lintlha, o ka tseba tsebo ena ea bohlokoa tlhahisong ea lisebelisoa tsa elektroniki, e hlahisang liboto tsa boleng bo holimo tsa FPC.
