Process of EMS
Professional Electronic Processing
Service Anytime
Electronic Manufacturing Services (EMS) encompass a range of processes related to the design, manufacturing, and testing of electronic components and assemblies. EMS companies provide specialized services, enabling businesses to outsource the production of electronic products, from printed circuit boards (PCBs) to complete electronic systems.
EMS companies play a vital role in industries such as telecommunications, consumer electronics, automotive, aerospace, and medical devices. Their services allow businesses to scale production rapidly while maintaining high-quality standards, all without the need for significant investments in manufacturing infrastructure.
SMT line layout & specs
Solder Application
Using a screen printing process, solder paste is precisely applied to the solder pads through a stencil.
Pick-and-place
The pick-and-place machine selects the required components from reels and accurately positions them onto the solder pads.
Bonding
The reflow oven heats the solder paste, effectively bonding the component leads to the circuit board.
Inspection
Each board undergoes inspection for faults and errors using 3D AOI and X-ray technology.
DIP line layout & specs
Insertion
Through-hole components are inserted into designated holes on the printed circuit board (PCB) in preparation for soldering.
Wave Soldering
Ensure consistency and cost-efficiency tailored for mass production.
Rework / Inspection
Correct any issues identified during inspection, such as repairing misplaced or improperly soldered components on the PCB.
Assembly
Ensure all components are fully aligned and securely fixed onto the printed circuit board (PCB).
Pressure test / Function test
Verify the assembled PCB’s durability and functionality under simulated operating conditions.
Inspection & Quality Control
Smart Component Rack
Intelligent parts storage management and pickup reminders to reduce errors and improve efficiency.
Solder paste heating/mixer
Set the heating/stirring time, which must be reached before it can be unlocked and removed, to prevent unstable solder paste quality.
3D SPI
Color images, which are rare in the industry, enable problems to be identified more clearly and quickly.
X-Ray
The first, last, and random samples from each work hour are also inspected using X-ray to ensure quality.
Electronic test
Verify that a device or component operates as intended and meets quality standards.
