Solder Preform yokhala ndi Flux ndi No Flux
Kupereka ma preform mumitundu yosiyanasiyana, makulidwe, ndi mitundu ya flux.Zinthu Zachikhalidwe zitha kupangidwa kuti zikhale ndi zinthu zapadera komanso zofunikira zazikulu.Ntchito zazikuluzikulu zikuphatikiza kufa kwa semiconductor, tchipisi ta LED ndi laser, ma fuse otentha, kusindikiza, mawonekedwe amafuta, zolumikizira ndi zingwe, vacuum ndi hermetic seals ndi ma gaskets, msonkhano wa PCB, cholumikizira chamakina, kusindikiza phukusi / chivindikiro.
Solder preforms amapereka voliyumu yeniyeni ya solder pa olowa aliyense solder kuti yunifolomu pa mkulu voliyumu.Izi zimapereka ntchito zophatikizira zogulitsa zochulukirapo ndikuchulukitsa zokolola kudzera pakutumiza kolondola & kuwongolera kwa solder pakulumikizana kulikonse.
Ma preforms amatha kupangidwa kuti agwirizane ndi kasitomala kukula kapena mawonekedwe aliwonse kuphatikiza ma rectangles, ma washer, ma disc, ndi mafelemu.Timapereka ma fluxes ndi zotsukira kuti tigwiritse ntchito ndi solder preforms.Ma chemistry omwe alipo akuphatikizapo RA, RMA, ndi No Clean.Ma Fluxes amatha kuperekedwa mumitundu yamadzimadzi ndipo amatha kukutidwa kale pa ma solder preforms.
Mawonekedwe
● Die attach of semiconductor, LED, ndi laser chips
● Ma PCB: Wonjezerani ma solder volume/fillet pa PCB kudzera m'mabowo
● Kusindikiza phukusi/chivundikiro
● Mawonekedwe a kutentha: Chip-to-lid / lid-to-heat sink
Mapadi okonzedweratu amagwiritsidwa ntchito makamaka pakulekerera kwazing'ono zomwe zimafuna njira zopangira misa ndi ntchito zomwe zili ndi zofunikira zapadera pa mawonekedwe a solder ndi khalidwe.Amagwiritsidwa ntchito kwambiri m'makampani ankhondo, oyendetsa ndege, kulumikizana ndi kuwala, kulondola kwamagetsi azachipatala, magetsi amagetsi ndi mphamvu, magalimoto amagetsi amagetsi atsopano, magalimoto osayendetsedwa ndi anthu, intaneti yazinthu ndi zina.
