Electronics - PCB Assembly Manufacturer

Surface Technology International Philippines, Inc.

Surface Technology International is a specialist Contract Electronics Manufacturer, serving world-class customers in high-reliability industries by providing a complete set of electronics design and manufacturing solutions in both printed circuit board assembly (PCBA) and full box-build manufacturing.

We are organised around four divisions: Manufacturing, Supply-Chain, Research & Development and Capital. Headquartered and operating from a manufacturing site in the UK since 1989, we purchased a second manufacturing facility in South East Asia in 2010 ; with both platforms equipped with the same machinery and processes – STI can now offer its full range of capabilities at an optimal cost point to meet most CEM requirements.

To facilitate a seamless transfer to higher-volume production overseas, our modern facility in South East Asia has been built to match the capabilities of our UK base.

STI Philippines is located in a specialist secure site administered by the Philippines Economic Zone Authority (PEZA) (http://www.peza.gov.ph/) in Cebu, where it holds ‘Pioneer’ status. Like the UK facility, it specialises in surface mount assembly, through-hole assembly, test and box-build. Strong links and daily communication with the UK facility using video conferencing and web-cams ensures that best practices are maintained across both sites. All our Operators are trained to IPC-A-610 and J-STD-001 Class 2 and 3.

This facility serves multiple customers in Asia, USA, UK and Continental Europe spanning several industry sectors such as automotive, medical, industrial and consumer.

Our Philippines capabilities include:

Surface Mount assembly – Using ASM Siplace pick-and-place machines, we can place down to 01005, 0.25mm BGA, to 30um accuracy. We have three lines composing of the D-Series and ultra-fast X-Series. The SMT facility will run 6 days a week, 24 hours a day, when required, giving a capability of nearly 5 million components per day.

Conventional through-hole assembly – Ourflow lines are capable of running 6 days a week, 24 hours per day. IPC-A-610 and J-STD-001 Class 2 and 3 standard. We have lead-free and tin-lead capability.

Wavesolder – Capability in lead-free solder alloy.

Test – The test facilities in Cebu include bed-of-nails ICT, bespoke functional test solutions and National Instruments PXI.

Box-Build and Test – Medium to high volume assembly and test. Bespoke cells are designed and laid out to provide the best process flow for each product.

Special Processes – Operators have been trained in the UK facility to IPC-7711/21 standards. The Cebu facility has BGA removal, replacement and reballing capabilities with CT scanning x-ray.
