Sample and Batch Electronic PCB Board SMT Service 94V0 FR4 for Wireless Communication PCB

Are you looking for a PCB supplier in China who can produce even 1 piece? Go with Linked Electronics, we

have no MOQs, you can order 1piece PCBA board at Linked Electronics, and we are really happy to quote you the price and work on the electronic prototype PCB project. 

At Linked Electronics, we provide PCB fabrication, PCB assembly and SMT stencils.

We can produce 2 layer PCB, multilayer PCBs, electronic FR4 PCB, aluminum Core PCBs, Rogers PCB, heavy copper PCB, quick turn PCB, Rigid-Flex PCB boards. 

All our raw material are the best in the PCB markets. For the FR4 substrate for example, we use shengyi, KB or ITEQ. That is the most expensive raw material in the market. For LED PCBs, we also use TAIYO soldermask, this raw material is 30% expensive than other soldermask.

Linked Electronics will also have very strict PCB inspection standard, we follow all the rules of  IPC standard. If your products has the application which is used in medical, communication or military application, you can request us to use IPC class 3 standard. 

RoHS management

We know how important our environment means to our human beings. Back in 2006, all our production procudure follows Rohs standard. At Linked, we perform our PCB production according to local goverment regulations. And all electronic PCBA and PCB Board produced by Linked Electronics, the PCB and PCBA manufacture in China,  will comply with Rohs.

Product compliant: RoHS
RoHS prohibited substances list :
NO. Name The upper limit(ppm=mg/kg)

Linked Electronics provides one-stop PCB/PCBA customization services. To meet all of customer's PCB/PCBA requirement is the goal that we pursue

1.To offer good quality PCB/PCBA, Linked Electronics will do many kind of testing to ensure quality before shipments

2.Outgoing test to check min PTH Cu thickness, Minimum surface Cu thickness, ENIG Au data,Ni info, Au layer adhesion testing, soldermask adhesion testing, silkscreen adhesion testing, Thermal stress testing, hardness testing, Twist testing, Bow testing

3.Microsection testing to check hole copper thickness, surface Cu thickness, Wrap copper thickness, Hole Wall Integrity, soldermask thickness and stack up.

4.E-test to inpsect any open/short circuit.

5. Final Visual Inspection before shipping to customers. In this PCB manufacture producure, scratch, board warp, board thickness, soldermask registration will be all checked. 

6.Thermal Stress Test to avoid any Delamination, Measling and others.

7.Solderability of PTH to avoid any discolor, Wrinkles, Blisters, Measling, Blow-Hole, Solermask peel off, and soldermask filled in hole-wall incompletely.

8. Outgoing and microsection report will be sent with the PCBs.
