PCBA Manufacturing
LEADER-Tech provides PCBA assembly, low to medium MASS production volume.
Our professional SMT factory has advanced equipment, such as the world-class stencil printing, SMT chip pick & place, solder reflow, and in-line testing and steel mesh manufacturing. AOI test machine and X-ray testing machines for quality check.
 
our main services for PCBA:

Surface Mount Technology
POE all products follow IPC2 standards. With 18 years' experience of placing BGA, FBGA, and small profile passives down to and including 0201, LEADER-Tech. offers a cost effective high yield solution to any SMT requirement.
 
Pin Through Hole
Capabilities to place tape and reeled radial components sizes. Maximum PCB size is 40" x 40".

RoHS Regulations
LEADER-Tech. have 2 kinds of solutions. Lead-free and leaded soldering process.

Selective Wave Solder
Having the Selective Wave soldering machines, LEADER-Tech achieves consistent quality and process control when assembling boards having multiple ground and power planes, high-current connectors or A-typical distribution of components. All AOI tested before QC. IPQC.
 
Conformal coating
Both dip-coating and vertical spray coating is available. Protecting nonconductive dielectric layer that is applied onto the printed circuit board assembly to protect the electronic assembly from damage due to contamination, salt spray, moisture, fungus, dust and corrosion caused by harsh or extreme environments. When coated, it is clearly visible as a clear and shiny material.

Complete box build
Complete 'Box Build' solutions including materials management of all components, electromechanical parts, plastics, casings and print & packaging material

In-Circuit Testing
In-Circuit Testing is commonly used in conjunction with AOI minimizing functional defects caused by component problems.
