PSi Technologies

PSi Technologies is a Philippine semiconductor services company focused on assembly, packaging, testing, and related design work for power semiconductor devices. The business was established in 1988 as Pacific Semiconductors Inc., commonly abbreviated as PSI, and developed around the manufacturing requirements of the power semiconductor market. Its activities cover outsourced semiconductor assembly and test services for devices used in power conversion and power management applications, as well as engineering support for customers developing power packages and other packaging solutions. The company’s service portfolio includes semiconductor assembly and a range of electrical and reliability-oriented tests. The documented testing capabilities include parametric testing, avalanche testing, reverse-recovery-time testing, integrated serial testing, package-isolation testing, and embossed carrier taping. These capabilities support power devices that must manage voltage, current, switching, thermal performance, and electrical isolation in demanding end products. PSi Technologies serves application areas that include telecommunications and networking equipment, computers and computer peripherals, consumer electronics, electronic office equipment, automotive systems, and industrial products. Its role is primarily business-to-business: rather than selling branded finished consumer devices, it provides manufacturing infrastructure, packaging expertise, and test capacity to semiconductor customers and electronics manufacturers. Ownership changed several times during the company’s development. RFM Corporation made a minority investment in the business in the late 1980s and became its majority owner in 1995. RFM later divested its interest in 2001. Integrated Micro-Electronics, Inc. acquired shares in 2010 as part of a strategy to provide an integrated hybrid power solution based on a multi-chip module and advanced manufacturing technologies. That transaction gave IMI a 56 percent majority stake. In 2012, IMI acquired the remaining minority interests and became the 100 percent owner of PSi Technologies. PSi Technologies operates as an IMI subsidiary. The company also owns 40 percent of PSiTech Realty, the holding company of Pacsem Realty, a real-estate business involved in acquiring, holding, developing, and disposing of real estate or related interests. This real-estate interest is separate from PSi Technologies’ core semiconductor assembly and test activities. The brand is positioned as a specialist manufacturing and engineering partner in power semiconductors. Its relevance comes from production know-how, packaging capability, testing breadth, and integration with the wider manufacturing resources of the IMI group. Public reference material identifies the company’s Philippine base and its technical scope, but does not provide sufficient current information to document its present executive leadership, detailed facility footprint, revenue, or customer roster.

PSi Technologies began operations in 1988 under the name Pacific Semiconductors Inc., or PSI. It was established to participate in the power semiconductor manufacturing market, a segment serving devices that convert, regulate, switch, or manage electrical power. From its Philippine base in Laguna, the company built capabilities in semiconductor assembly, power packaging, and electrical testing rather than focusing on the design and sale of finished electronic products under a consumer-facing brand. The company’s manufacturing and engineering scope expanded around the requirements of power semiconductor customers. Its services came to include assembly for power conversion and power management devices, package design support, and a collection of specialized tests. These included parametric testing, avalanche testing, reverse-recovery-time measurement, integrated serial testing, and package-isolation testing. PSi Technologies also provided embossed carrier taping, a packaging and handling service used to prepare semiconductor devices for downstream production and automated component placement. RFM Corporation was an early investor. It initially held a minority interest in the late 1980s and later became the majority owner in 1995. RFM subsequently divested its interest in 2001, marking a change in the company’s ownership structure. Public reference material does not identify all intermediate ownership arrangements or provide a complete chronology of the company’s facilities and customer relationships. A significant later change occurred in 2010, when Integrated Micro-Electronics, Inc. acquired shares in PSi Technologies. IMI described the transaction in the context of a strategy to provide an integrated hybrid power solution based on a multi-chip module incorporating advanced manufacturing technologies. The investment gave IMI majority control, with ownership reported at 56 percent. The acquisition connected PSi Technologies’ power semiconductor capabilities with the broader manufacturing platform of IMI. In 2012, IMI purchased the interests held by minority shareholders and became the sole owner of PSi Technologies. The company thereafter operated as an IMI subsidiary. Its business remained centered on power semiconductor assembly, package-related design and manufacturing, and testing for devices used in a broad range of markets. Those markets include telecommunications and networking, computers and peripherals, consumer electronics, electronic office equipment, automotive systems, and industrial products. PSi Technologies also owns 40 percent of PSiTech Realty. PSiTech Realty is described as the holding company of Pacsem Realty, a real-estate company whose activities include acquiring, holding, developing, and disposing of real estate or related interests. This affiliated investment forms part of the corporate history associated with PSi Technologies but is distinct from its principal semiconductor-services operation. The available public material presents PSi Technologies as an established specialist supplier within the outsourced semiconductor assembly and test ecosystem. Its strategic value lies in power-device packaging, production support, and test capabilities, while its ownership by IMI provides a connection to a larger electronics manufacturing group. Information available in the cited reference does not establish a detailed current management roster, standalone financial results, current customer list, or a separate public stock listing for PSi Technologies.
