Kakaretso ea Sehlahisoa
Moetso oa sehokelo sa SMA female PCB ke SMA-KE SMT.SMA series ke lihokelo tsa 50 ohms RF tse tsebahalang, tse sebelisang khokahanyo ea khoele, tse fanang ka ts'ebetso e tšepahalang le e ntle haholo ea motlakase ka maqhubu a phahameng. Li sebelisoa haholo sebakeng sa aero le aero, libetsa tsa sesole, marang-rang a se nang mohala, le puisano ea ordata ea lisebelisoa tsa microwave. Hape ba hokela lithapo tsa semi-flex kapa semi-rigid tse sebetsang ho fihla ho 18GHz.
Sehokelo sa SMA ho Mekhoa ea Khokahano ea PCB
1. Khokahano ea plug e otlolohileng
Position e Nepahetseng le Kenyeletso Kenya ka bonolo le butle, ho etsa bonnete ba hore phini e 'ngoe le e 'ngoe ea plug e tsamaisana hantle le lesoba le holimang. Qoba ho sebelisa matla a feteletseng nakong ea ho kenya ho qoba ho koba lithakhisa tsa plug kapa ho senya masoba a ntseng a hola ho PCB.
Sireletsa Lithakhisa: Sebelisa li-tweezers ho koba lithakhisa tsa plug ka hloko e le hore li ka lekana hantle ho PCB. Sena se etsa bonnete ba hore plug e lula e tsitsitse le ho thibela ho sisinyeha leha e le hofe nakong ea ho soasoa, ho netefatsa hore{1}e sebetsa ka boleng bo holimo.
Ho Soldering ka nepo: Preheat iron soldering ho 300℃-350℃. Kenya phallo e nyane sebakeng sa ho kopana lipakeng tsa phini le PCB. Ebe, sebelisa khoele ea solder ho solder pini ho PCB pad. Nakong ea solder, laola ka thata nako le mocheso, ho boloka pini e 'ngoe le e' ngoe e soasoa ka metsotsoana e 2-3 ho thibela manonyeletso a batang a solder, li-circuits tse khutšoanyane, kapa ho senya PCB ka lebaka la mocheso o feteletseng kapa ho senya nako e telele. Ka mor'a hore soldering e phethoe, khaola lithako leha e le life tse feteletseng ka makhethe ka lithapo tsa terata.
2. Surface Mount Connection
Preheating le Soldering: Lihokelo tsa Surface mount SMA li hloka ho hlajoa ka ontong ea ho phalla hape. Thempereichara ea preheat e lokela ho laoloa pakeng tsa likhato tse 150 le 200 ho netefatsa hore solder e qhibiliha ka ho feletseng 'me e theha khokahanyo e ntle. Qoba ho chesa haholo nakong ea solder ho thibela tšenyo ea sehokelo kapa PCB.
