Defining excellence with a 0.001% Defect Rate: The Art of Manual Hand Soldering at Bigmate:
In today’s fast-moving electronics manufacturing industry, many companies rely on robotic soldering to meet production speed and efficiency demands. However, at Bigmate, we believe that human craftsmanship and precision remain the key to delivering high-quality soldering results.
Our manual hand soldering service is driven by expertise, dedication, and attention to detail — ensuring every connection meets the highest standards of performance and reliability.
What Type of Products are Suitable for Hand Soldering
The vast majority of high-volume and small-component assembly are handled by Surface Mount Technology (SMT), but hand soldering is crucial for parts that need accuracy, adaptability, or customization.
Products suitable for hand soldering include:
- Prototypes and low quantity builds – hand soldering provides flexibility without the setting up of machine for products that are in testing phase or produced in small batches
- Through-Hole Components – Huge components must be soldered manually since it cannot always be processed through SMT Lines.
- Connectors and Specialty parts – In order to ensure durability and alignment, certain connectors, wires, and mechanical parts need precise manual placement
- Rework and Repair Jobs – Circuit boards can be fully functionally restored through expert hand soldering when components need to be changed or modified.

Human Touch in Every Detail
While machines may deliver speed, they lack adaptability. Our Workers can analyze, adjust, and refine soldering work in real time — something automation simply can’t match. This human touch ensures superior quality and attention to detail for every component we handle.
The bigmate advantage
Choosing Bigmate’s manual soldering services means partnering with a team that values both technology and human expertise. We understand that not every task can be left to automation — especially when quality, precision, and reliability are non-negotiable.
Bigmate’s strength lies in our skilled workforce, useful equipment, and strict working standards — all combined to maintain product excellence and zero defect (NG) items.
Inside the Process: How We Detect Defects in PCB and SMT Assembly
At Bigmate, we take pride in maintaining an incredibly low 0.001% defect rate — and we’re continuously striving to reach zero defects. Achieving that goal starts with a strong commitment to quality at every stage of our PCB (Printed Circuit Board) and SMT (Surface Mount Technology) assembly process.
| YEAR | YIELD RATE | DEFECTIVE RATE |
|---|---|---|
| 2025 | 99.99 % | 0.01% |
| 2024 | 99.99 % | 0.01% |
| 2023 | 99.99 % | 0.01% |
| 2022 | 99.73% | 2.07% |
Every step is carefully monitored, tested, and refined to ensure that only the best products reach our customers. Through a series of inspections and tests — from detailed visual checks to in-circuit and functional testing — we make sure that even the smallest imperfections are detected and corrected before final delivery. This process is our way of turning precision into performance and commitment into customer trust.

Type of Process
Purpose
VISUAL INSPECTION ( VI )
To ensure that all components are correctly placed, soldered, and free from visible defects such as misalignment, cracks, or contamination before proceeding to the next stage of testing.
INCIRCUIT TEST ( ICT )
To verify the electrical performance and connectivity of individual components and circuits on the PCB, ensuring there are no open circuits, shorts, or faulty parts.
FUNCTIONAL CIRCUIT TEST ( FCT )
To confirm that the assembled product operates according to its intended design and specifications by testing its overall functionality under simulated working conditions.
FUNCTIONAL CIRCUIT TEST ( FCT )
To confirm that the assembled product operates according to its intended design and specifications by testing its overall functionality under simulated working conditions.
FINAL VISUAL INSPECTION ( FVI )
To assemble and integrate all electrical components and circuits to form a working system that supports the product’s designed functionality.
