What Loranger does

Loranger International Corporation (LIC) is a privately held US manufacturer of burn-in and test sockets, printed circuit boards, and environmental chamber systems for the semiconductor and electronics manufacturing industry. Founded approximately in the 1970s and headquartered in Warren, Pennsylvania, the company has accumulated over 50 years of specialized manufacturing experience. Its product portfolio centers on a catalog of more than 3,500 burn-in and test socket designs, including over 1,400 QFN (Quad Flat No-Lead) styles, spanning package types such as BGA, DIP, LGA, PGA, PLCC, SIP, SMD, TO, Flat Pack, LCC, and Microwave/Hybrid. Sockets support fine-pitch packages down to 0.22mm and incorporate advanced thermoplastic materials including PEEK, PEI (Ultem), LCP, PPS (Ryton), PES, and PAI (Torlon), with options for non-magnetic construction, Kelvin contacts, and 50-ohm impedance designs for microwave applications. The company maintains EU REACH and RoHS compliance for European and regulated market access.

Loranger sells through a sales-led motion staffed by Sales Engineers who review customer package drawings to recommend and quote appropriate socket solutions, complemented by an online catalog platform (catalog.loranger.com) with advanced search, express ordering, and quote request capabilities. Pricing is quote-based with tiered volume discounts spanning 1-unit through 2,500+ unit quantities, and standard lead times of 2-4 weeks. The company positions itself as a "Tariff Free for US Customers" domestic manufacturer, a meaningful differentiator in a category where offshore socket sourcing is common. Loranger serves enterprise customers in defense, aerospace and space exploration, automotive electronics, communications, and specialty applications such as music electronics, with worldwide distribution coverage.

The company is privately held with no disclosed institutional investors, parent company, or ownership changes documented in available sources. Operational footprint includes the Warren, PA headquarters and a sales office covering Asia and North America West. Headcount is in the 51-100 employee range, and revenue, funding, and detailed financial information are not publicly disclosed.
