Ib tus pin yuav tsum muab me me, tseem muaj ntau cov khoom uas muaj fim rau txoj kev loj hlob ntawm me me thiab ntais, yov thiab loj, me, muaj ib cov qhov siab yuav tsum, cov khoom no yuav muaj ntau dua sophisticated, xws li hlau los tswj tus xaiv rau kev ncua deb ntawm 0.6 hli thiab 0.8 hli, siab ceev, siab ceev, tus me zoo li siab xav loj. Miniaturization yog ib tus nkaus xwb nawj Center yov me, kev kub ceev yog cov tub ntxhais.
Luag hauj lwm ntawm ib koob yog nyob rau hauv Circuit Court sim los yog kev rho tawm ntawm kev ua si sib txawv, choj tso cai, xav tias tus ua hauj lwm hauv tam sim no los yog pib ntsais koj teeb. Feem ntau yog siv rau Pai tus niam, roos lub Board rau pawg thawj coj saib kev twb kev txuas los yog siv rau lub sam xauv nees thaiv, roos lub Board rau kab; yuav hais tau rau lub Board thiab tswj yus qhov zoo sib xws. Thaum cov neeg uas xaiv plaub tus nawj npawb, yuav xub muab mus rau hauv tus account Tswjhwm nqi, lwm tus siab zoo, siab stability thiab tsim nta ib zaug xwb nawj xwb. Yuav kom zam hauv designers underestimate qhov tseem ceeb ntawm ib tus PIN nkaus xwb nyob rau hauv qhov kev tsim no los, peb muab ib co tswv yim. Uas tsim lub sij hawm yuav tsum muaj ib tug coj qws tsim; yog muaj ib tug tsim robust ua luaj rau.
Leej tib rab koob siv thiab ua raw siv cov ntaub ntawv teeb dawb, ntawm cov xim nyiaj thiab npib tsib xee, pib weldability, kub laus solderability degradation los ntev cia yog loj. Kub-plated qab npaj rau cov kua hauv lub cev decorations kuj yuav siv rau hluav taws xob kev kawm yuav tsum yog tsis loj heev, tab sis cov siab anti-tarnishing dawb, solderability zoo yuav tsum sau los teb.
