Pad Printing

Pad printing is an efficient method for transferring 2D images onto 3D automotive parts, including curved and irregular surfaces. It delivers sharp detail, vibrant color, and strong adhesion using specialized inks suited to various materials.

A soft silicone pad adapts to complex shapes for precise image transfer. This process is ideal for branding, markings, and customization.

High-performance pad printing machines ensure consistent quality, excellent registration, and durability—making them essential for demanding automotive applications.

Surface Mount Technology

Surface‑Mount Technology (SMT) involves mounting electronic components directly onto printed circuit boards (PCBs) with exceptional precision.

At Polyfit, our Class 10K cleanroom houses a fully automated SMT production line featuring high‑speed pick‑and‑place machines capable of placing up to 90,000 components per hour. Our process includes solder‑paste inspection (SPI), automated‑optical inspection (AOI), and an auto‑rejection conveyor system to ensure continuous, uncompromised quality control throughout the production cycle.

Our Services

PCB Assembly

Using advanced equipment and techniques, we provide precise and efficient PCB assembly, including SMT, through-hole, and mixed technology assemblies.

Quality and Testing

Our SMT quality laboratory is equipped with advanced tools such as a thawing machine, viscometer, stencil‑illumination system, and baking oven — enabling defect‑free, high‑reliability PCB assemblies. We adhere strictly to IPC‑A‑610 and other international quality standards. Each board undergoes visual and automated testing to guarantee consistent performance.

Supply Chain Management

Our robust supply chain management solutions ensure timely, cost-effective delivery of components and materials, supported by global sourcing and strategic partnerships.

Production Flexibility

From rapid prototyping to full‑scale production, our flexible systems handle both low‑volume and high‑volume manufacturing efficiently and accurately. We provide comprehensive support across every stage — from component sourcing and design validation to assembly, testing, and packaging.

Aftermarket Services

We offer comprehensive repair and refurbishment services, ensuring your products perform optimally throughout their lifecycle.

Class 10K Cleanroom Environment

Our Class 10K (ISO 7) cleanroom ensures that airborne particle concentration remains below 10,000 particles per cubic foot, protecting sensitive electronic components from contamination. The environment maintains controlled temperature, humidity, and electrostatic discharge (ESD) protection, ensuring consistent soldering quality and long‑term product reliability.
