Ukuthengwa kwabasebenzi kwinkqubo yokuthenga, banengxaki yokukhetha isinxibelelanisi, njengemfuneko yokuqwalasela isantya sothumelo, ingqibelelo yesiginali, iingxaki zokusebenza, ezifana nobukhulu kunye nemilo, kodwa eyona mfuneko ibangela inkxalabo yethu kukumisela indlela yokuphelisa. isinxibelelanisi, oku kungenxa yokuba uninzi lwezicelo lufuna uhlobo oluthile lwetekhnoloji ukuze luhambelane neemfuno zoyilo lwesinxibelelanisi, Ke zithini iiteknoloji zokugqibela zesinxibelelanisi?
Itekhnoloji yokuphelisa isiqhagamshelo ikakhulu ibandakanya itekhnoloji yokuphelisa umngxuma (THT), itekhnoloji yokuphelisa umphezulu wentaba (SMT), itekhnoloji yokuphelisa itekhnoloji yokuphelisa umngxunya, kunye netekhnoloji yokuphelisa itekhnoloji.Iinkcukacha zezi zilandelayo:
I-1, isinxibelelanisi ngeteknoloji yokuphelisa umngxuma (THT).
Ukupheliswa komngxuma kwakuxhaphakile ngeentsuku zokuqala, kunye nezihlanganisi ezichukumisayo okanye ezikhokelela kwimingxuma kwiPCB.Amacandelo ngomngxuma afaneleke kakhulu kwiimveliso ezithembeke kakhulu ezifuna imidibaniso eyomeleleyo phakathi kweemaleko zePCB.
I-2, iteknoloji ye-connector surface mount end (SMT).
Ukusetyenziswa kwe-surface-mount termination of this technology, i-connector inokufakwa ngokuthe ngqo phezu kwe-PCB kunye ne-welding manual endaweni, inokusebenzisa iindlela zokuphinda ziphinde zifakwe / ze-wave soldering kufuneka zilungiswe kwindawo.
I-3, i-pin yokudibanisa ngokusebenzisa i-teknoloji yokuphela kwe-welding ye-welding
Itekhnoloji yokuphela kwe-welding ye-hole reflow ye-connector igqityezelwa ngoomatshini abazenzekelayo, ngaphandle kwenkqubo yezandla kunye ne-wave soldering.Izihlanganisi zibekwe ngokukhululekileyo kwimingxuma kwipleyiti kwaye zibekwe phantsi komatshini ukwenzela ukuba i-solder ene-liquefied ibuyele kwi-plate kwiqondo lokushisa eliphezulu.Ngenxa yesenzo se-capillary, intlama ye-solder etyhidiweyo itsalela i-solder kwipleyiti kwaye ingene emngxunyeni, yenza i-bond esisigxina phakathi kwe-solder paste kunye ne-connector lead, kwaye emva koko i-solder eseleyo iyasuswa.
I-4, uxinzelelo lokudibanisa oluhambelana neteknoloji yokugqibela
Ukupheliswa kwe-Press-fit ngokuqhelekileyo ku-solder-free, oku kunceda ukunciphisa iindleko ezipheleleyo zezicelo ze-connector, kwaye ngokuqhelekileyo kuyacetyiswa ukuba kusetyenziswe ezi ntlobo zezihlanganisi ezinezixhobo ezithile zokuqinisekisa ukuba izinto zifakwe ngokulinganayo kwaye zifakwe ngokupheleleyo.
