With a team of over 200 skilled technicians and engineers, they balance speed with quality, making them a top choice for time-sensitive projects.

Located in the heart of Jakarta's industrial zone, PT. Jakarta Electronics Assembly (JEA) has built a 15-year legacy on customer-centric service. Unlike some suppliers that focus solely on high volume, JEA thrives on flexibility, offering everything from low-volume prototype runs to mass production. Their secret? A modular production setup that can switch between projects without sacrificing efficiency.

JEA's service portfolio includes SMT assembly, through-hole soldering, conformal coating, and functional testing. They've recently expanded their capabilities to include smt assembly with components sourcing , partnering with global distributors to secure hard-to-find parts at competitive prices. This has made them a go-to for startups and SMEs that lack the resources for in-house component management.

Quality is ingrained in their process. JEA is ISO 13485 certified, making them a trusted partner for medical device manufacturers, and they strictly adhere to RoHS compliance for environmentally conscious clients. "Their attention to detail is unmatched," noted a quality assurance manager at a leading Indonesian medical tech firm. "Even on complex boards with 500+ components, their defect rate stays below 0.01%." With a 24/7 production line and dedicated project managers, JEA ensures clear communication and on-time delivery, solidifying their reputation as a reliable partner.

Surabaya, Indonesia's second-largest city, is home to PT. Surabaya Precision Tech, a supplier that has carved a niche in high precision SMT PCB assembly for the aerospace and defense sectors. Founded in 2010, the company has invested heavily in advanced machinery, including ASM Siplace TX placement systems and DEK printers, enabling them to handle ultra-fine-pitch components (down to 0.3mm pitch) and flexible PCBs with ease.

What truly distinguishes Surabaya Precision Tech is their in-house testing lab, equipped with X-ray inspection, AOI (Automated Optical Inspection), and functional test stations. This allows them to catch defects early, reducing rework and ensuring compliance with stringent aerospace standards like AS9100. "We once had a project requiring 10-layer PCBs with BGA components," said an engineer at a local aerospace subcontractor. "Surabaya Precision Tech not only assembled them flawlessly but provided detailed X-ray reports for every batch—something many suppliers skimp on."

While precision is their forte, they also understand the importance of cost management. By optimizing their supply chain and offering low cost SMT processing service for high-volume orders, they balance quality and affordability. Their client base spans Indonesia, Singapore, and Malaysia, with a growing focus on exports to Europe. With a team of 150+ employees and a 8,000-square-meter facility, Surabaya Precision Tech is poised to remain a leader in high-precision SMT for years to come.
