Mofuta oa holim'a marulelo oa SMT

Lisebelisoa tse ngata tsa elektroniki ha li e-so behoe holim'a metsi ho sebelisoa SMD.Ka lebaka lena, SMT e tlameha ho amohela likarolo tse ling tsa lesoba.Likarolo tse holim'a marulelo, tse sebetsang le tse sa sebetseng, ha li khomaretsoe ho substrate, li theha mefuta e meraro e meholo ea likopano tsa SMT - tse atisang ho bitsoa Mofuta oa I, Mofuta oa II le Mofuta oa III.Mefuta e fapaneng e sebetsoa ka tatellano e fapaneng, 'me mefuta eohle e meraro e hloka lisebelisoa tse fapaneng.

1. Likopano tsa mofuta oa III tsa SMT li na le likaroloana feela tsa "resistors, capacitor le transistors" tse khomaretsoeng ka tlase.

Likarolo tsa 2.Type I li na le likarolo tsa holim'a thaba feela.Likarolo li ka ba lehlakore le le leng kapa mahlakore a mabeli.

3. Likarolo tsa Mofuta oa II ke motsoako oa Mofuta oa III le Mofuta oa I. Hangata ha e na lisebelisoa leha e le life tse sebetsang holim'a holim'a metsi ka lehlakoreng le ka tlaase, empa e ka ba le lisebelisoa tsa discrete holim'a metsi ka lehlakoreng le ka tlaase.

Haeba sekontiri se seholo ebile se le setle, ho rarahana ha kopano ea SMT ka thepa ea elektroniki ho tla eketseha.

Ultra-fine pitch, QFP (Quad Flat Pack), TCP (Tape Carrier Package) kapa BGA (Ball Grid Array) le likaroloana tse nyane haholo tsa chip (0603 kapa 0402 kapa tse nyane) li sebelisetsoa likarolo tsena hammoho le setso (50 mil pitch). )) sephutheloana sa holim'a thaba.

Mekhoa ea lisebelisoa tse tharo tse holim'a holim'a metsi e kenyelletsa - li-adhesives, solder paste, ho bea, ho kopanya le ho hloekisa ho lateloa ke ho hlahloba, ho hlahloba le ho lokisa.

Chengyuan Industrial Automation, moetsi oa lisebelisoa tsa SMT ea hloahloa.
