Thanks to an American customer's trusting in our service

We’d like to thank Mr.B here,  two years continous orders, he is very professional, and we have pretty good communication. He is very satisfied with our service, and we finally come to a 50k pcs mass production order: bare PCB fabrication, PCB assembly, component procurement.

We must mention this: our skilled engineer team guarantee original component verifying or specified brand, also there is AOI automatic inspection, x-ray inspection for all BGA parts… All processes are under qualified control, you don’t have to worry about anything,  because you have a responsible team in Treepcb work for you. Anyway, a trial order of yours will prove easily what we say here.

Warm welcome your visiting to our factory if you are looking for one stop service: PCB + PCBA

We'd like to share some components we've ordered.

SPC1012T  Texas Instruments

DESCRIPTION

The SPC101XX is the N-and P-Dual Channel enhancement mode power field effect transistors are produced using high cell density, DMOS trench technology. This high density process is especially tailored swiching performance. These devices are particularly suited for low voltage application such as notebook computer power management and other battery powered circuits where high-side switching,low in-line power loss,and resistance to tansients are needed.

amplitude control, receiver equalization, and link integrity status

SN1108XX Texas Instruments

1 General Description

SN1108XX is a high-performance integrated circuit to bridge USB and Flash

memory. It provides a flexible and cost efficient single chip solution for external

storage applications that intend to utilize the convenience of USB. To help the system

manufacturers to build high quality, low cost USB storage systems, several special

features are implemented. The embedded translation table helps the system makers to

design a high performance NAND type flash device but still keeps the cost low. The

proprietary randomization algorithm effectively extends the lifetime of the flash

memory, ensuring the robustness of the system. The real time ECC correction keeps

the data integrity while still maintains the high data transfer rate.
