Printed Circuit Board Manufacturing
From Core to Circuit
How JosephSan Delivers High-Performance Bare PCBs and Assembly Solutions
At JosephSan Private Limited, we believe that great electronics start with the foundation: the Printed Circuit Board (PCB). While we provide complete Printed Circuit Board Assembly (PCBA) services, our journey always begins with producing the right bare PCB that matches each customer's precise technical, functional, and regulatory requirements.
What sets JosephSan apart is our approach. Our team manages JosephSan’s bare PCB manufacturing processes with meticulous care, manufacturing expertise, and close supervision.
JosephSan’s Bare PCB Manufacturing Strength
Our manufacturing capabilities include:
-
2-layer to 20-layer multilayer PCBs, including HDI boards
-
Flex, Rigid-Flex, and Aluminum-backed PCBs
-
Production for IPC Class 2 and Class 3 standards
-
Automotive-grade and medical-grade PCBs, manufactured under strict quality systems
-
In-house PCBA capabilities, with experience in high-value, high-precision global projects
Our PCB factories operate under stringent international standards, including ISO 9001, ISO 14001, IATF 16949, and ISO 13485. Our factories, equipped with smart automation, robotic testing, and multilayer processing, allow us to deliver exceptional quality for a wide range of industries: automotive, medical, industrial control, IoT, and consumer electronics.
Thermal Power
High-Spec Aluminium Substrate for Heat-Intensive Applications
We utilize materials engineered for thermal reliability and electrical endurance for aluminum-backed PCBs, especially for high-thermal applications like LED lighting, power electronics, and industrial control.
Key features of our aluminum substrate include:
-
High thermal conductivity: ≥2.2 W/m·K to ≥4.0 W/m·K
-
UL certified with 94V-0 flame rating
-
Supports copper thicknesses from 1 oz to 6 oz
-
Excellent breakdown voltage, peel strength, and moisture resistance
-
Suitable for 1-layer to 6-layer aluminum PCBs
-
Compatible with 1060, 5052, and 6061 aluminum grades
Our engineering team selects and tests these materials to ensure optimal performance in thermally demanding environments.
JosephSan’s In-House Expertise: IPC-A-610 Class 3 Certified Engineers
While our engineers deliver top-tier bare PCBs, our Singapore-based engineering team ensures the quality of every assembled board. Our technicians include IPC-A-610 Certified IPC Specialists who have completed the full Application Specialist training, covering modules from general soldering and high-voltage soldering to through-hole, SMT, and hardware assembly. We uphold IPC Class 3 workmanship standards—the highest in the electronics industry—especially for mission-critical assemblies.
Quiet Excellence, Global Performance
We don’t boast about where the PCB is made. We focus on how it performs. Whether it’s a 2-layer board for industrial sensors or a 20-layer HDI board for medical imaging, we work quietly behind the scenes to ensure that the right factory, material, and process are selected and supervised for each job.
We deliver end-to-end PCB and PCBA solutions for customers who demand reliability, traceability, and uncompromising quality through our engineers, rigorous quality control, and our IPC-certified engineering excellence.
