FAQ
Q: Puas yog PCM (Kev Tiv Thaiv Circuit Module) suav nrog?
A: Yog. Txhua chav nyob suav nrog kev tsim ua - hauv PCM los tswj cov ntsuas kev nyab xeeb thiab xyuas kom ntev - lub sijhawm ruaj khov.
Q: Peb puas tuaj yeem thov kev cai txhuas hlau txuas thiab txuas?
A: Yog lawm. Peb muab cov kev pabcuam xaim xaim nrog rau cov khoom sib txuas tshwj xeeb (JST, Molex) thiab kev cai xaim ntev.
Q: Lub sij hawm ua khoom loj loj yog dab tsi?
A: Rau cov qauv qauv, 5-7 hnub ua haujlwm. Rau kev txiav txim OEM customized, lub sijhawm ua haujlwm feem ntau yog 15-21 hnub nyob ntawm cov khoom siv tshwj xeeb.
Q: Koj puas txhawb nqa engineering qauv?
A: Yog lawm, peb muab cov qauv rau kev kuaj xyuas engineering thiab kev tsav tsheb khiav kom ntseeg tau tias cov khoom siv zoo meej.
Q: Koj txais txoj kev them nyiaj dab tsi?
A: Peb lees txais T / T, L / C, PayPal, Western Union, thiab Alibaba Trade Assurance. Cov nqe lus them nqi yooj yim tuaj yeem tham txog ntev -kev koom tes.
Q: Koj lub sijhawm lav yog dab tsi?
A: Peb muab 12 lub hlis lav. Yog tias qhov teeb meem zoo tau lees paub, peb muab kev hloov pauv dawb tom qab kev ntsuam xyuas.
