Ogulira ogwira ntchito pogula, ali ndi vuto losankha cholumikizira, monga kufunikira koganizira liwiro la kufalikira, kukhulupirika kwa chizindikiro, zovuta zogwirira ntchito, monga kukula ndi mawonekedwe, koma chofunikira kwambiri chomwe chimayambitsa nkhawa yathu ndikuzindikira njira yochotsera. cholumikizira, izi ndichifukwa choti mapulogalamu ambiri amafunikira ukadaulo wamtundu wina kuti ufanane ndi zofunikira za kapangidwe ka cholumikizira, ndiye maukadaulo omaliza a cholumikizira ndi chiyani?
Ukadaulo wothetsera cholumikizira makamaka umaphatikizira ukadaulo wa through-hole terminating (THT), ukadaulo wa Surface Mount Terminating (SMT), ukadaulo womaliza wa pin through-hole reflow welding, ndi ukadaulo wotsatizana ndi atolankhani.Zambiri ndi izi:
1, cholumikizira kudzera muukadaulo wotsekera dzenje (THT).
Kutha kwa dzenje kunali kofala m'masiku oyambilira, zolumikizira zimagwira kapena kutsogolera pamabowo a PCB.Kupyolera mu dzenje zigawo zikuluzikulu ali bwino kwambiri kudalirika mankhwala amene amafuna kugwirizana kwambiri pakati PCB zigawo.
2, ukadaulo wolumikizira pamwamba pa phiri (SMT).
Kugwiritsa ntchito kutha kwa teknolojiyi, cholumikizira chikhoza kukhazikitsidwa mwachindunji pamwamba pa PCB ndi kuwotcherera pamanja m'malo mwake, angagwiritsenso ntchito njira zopangira reflow / wave soldering ziyenera kukhazikitsidwa pamalo.
3, cholumikizira pini kudzera mu dzenje reflow kuwotcherera mapeto luso
The kudzera dzenje reflow kuwotcherera mapeto luso cholumikizira makamaka kumalizidwa ndi makina basi, popanda pamanja ndi mafunde soldering ndondomeko.Zolumikizira zimakhazikika momasuka m'mabowo mu mbale ndikuyika pansi pa makina kuti solder yamadzimadzi ibwererenso ku mbale pa kutentha kwakukulu.Chifukwa capillary kanthu, phala wosungunula solder amakoka solder mu mbale ndi dzenje, kupanga mgwirizano okhazikika pakati pa solder phala ndi cholumikizira amatsogolera, ndiyeno solder otsala amachotsedwa.
4, cholumikizira kukakamiza kofanana ndi ukadaulo womaliza
Kutha kwa Press-Fit nthawi zambiri kumakhala kopanda solder, zomwe zimathandiza kuchepetsa mtengo wonse wa zolumikizira zolumikizira, ndipo nthawi zambiri tikulimbikitsidwa kugwiritsa ntchito zolumikizira zamitundu iyi ndi zida zapadera kuti zitsimikizire kuti zinthuzo zimayikidwa mofanana komanso mokwanira.
