SMT

K&P Co., Ltd. provides the best service
with our unique technical expertise.

Since 2003, in the field of Surface-Mount Technology (SMT), we have mass-produced a diverse range of mixed-size components (from 0402 chips to 88mm odd-shaped materials, Stick (bulk), Tray ICs, etc.), applied lead-free production capabilities and reliability assessments. In the IMT sector, we have ensured customer quality and reliability through Wave Soldering, In-Circuit Testing (ICT), Functional Circuit Testing (FCT), coating, firmware inspection, aging tests, and thermal shock assessment. For the growth of the SMT technology sector, we are actively expanding our micro-assembly technology (0201 Chip, 0.3mm Ball) and mixed assembly techniques. We are committed to providing global solutions by integrating Smart Factory, automation, and robotics technologies.

Leveraging our solid mass production experience in mobile cameras, 3D sensing modules, TVs, solar panels, and network repeaters, we manufacture SMT with differentiated technical process.

Securing mass production capabilities through optimal management of printing, placement, and curing conditions on ceramic substrates, along with traceability and timely inspection management system, ensuring reliability through shear and thermal shock assessments, operating a Clean Room (class 3,000), and obtaining water-soluble solder printing, placement, and cleaning technologies for semiconductor and medical device cleaning; moreover, we pursue a One Stop Service through SMT, IMT, ICT, FCT, coating, aging, and assembly processes.

The IVI System, enabled by the LED Array for Automotive BLU, offers
drivers and passengers a range of functional services through an
information and entertainment system within the vehicle.

PROCESS

01. Screen Printer

The process of printing solder paste in precise locations and volumes on the PCB electronic board pads

02. SPI

The process of inspecting and determining the position (X, Y) and volume (Volume, Height) of the solder paste printed on the PCB electronic board pads

03. Mount

The process of mounting electronic components (Cap, Resistor, IC, etc.) quickly and precisely at predetermined locations (X, Y, Th) on the printed PCB electronic board

04. M-AOI

A process that ensures consistent quality by checking if parts are accurately attached to the circuit board (missing, positioning, misalignment, etc.).

05. Reflow

A process that joins electronic components and PCBs through the melting and curing of solder paste.

06. AOI

An automated optical inspection process that scans with an LED light source to evaluate the mounting and soldering state of electronic components against inspection standards.

07. Robot Soldering

Automation of FPCB and Metal PCB soldering using robots enables quality and reliability assurance.

08. Flux Cleaning

A process using dedicated cleaning solutions and ultrasonics to remove residual flux.

09. Parking Marking

A process that encodes production information for marking to track production date, PKG information, and production sites.

10. Ambient Illumination Test

A test process performed to verify the proper operation of LED (Light Emitting Diode) products.

11. Photometric Measurement (Integrating Sphere)

A process that quantifies the luminous flux (light output) of LEDs and measures the light output in specific wavelength or spectrum ranges.

12. Visual Inspection

A visual inspection process based on agreed standards to meet customers' high-quality levels.

13. Shipping/Packaging

A process of product packaging and issuing shipping certificates in accordance with packaging standards agreed with customers.
