Metcal PT4-4000 and PT4-8000 Series 4-Zone Circuit Board Preheaters deliver thermal control for advanced electronics manufacturing and rework applications. Using Resistive Radiant Heat Technology, the systems radiate heat from a ceramic plate through a tempered glass surface, eliminating hot spots and ensuring consistent temperature distribution across the board. Each unit features four independently controlled temperature zones to accommodate a wide range of PCB sizes and thermal profiles, with real-time feedback from external thermocouples that continuously monitor and adjust heat output for maximum accuracy.

Advanced temperature control modes and programmable thermal profiles enable repeatable, application-specific performance, while enhanced flexibility makes the preheaters ideal for high-density assemblies, multilayer boards, and thermally demanding components. Designed to support both production and repair workflows, the PT4 Series integrates seamlessly into processes ranging from consumer electronics and data center hardware to aerospace, defense, and medical devices. The series is compatible with Metcal’s premium circuit board holders, which provide stable, adjustable support during heating and rework operations.
