JBC PHSE-1KB Preheater Set, ESD Safe, 120V, 800W, 50 - 250°C, For PCBs Up To 5" x 5"

JBC PHSE-1KB 120V Preheater Set for PCBs up to 5” x 5”

Indispensable for avoiding thermal shock on multilayer PCBs while reworking

The JBC PHSE-1KB is a PCB preheater system designed to minimize thermal shock during rework operations on multilayer printed circuit boards. Combining a preheater with the PHSS PCB support, this set provides a controlled heating platform for small- and medium-sized PCB assemblies commonly found in electronics manufacturing, repair, and rework environments.

With a heating area of up to 5" x 5" and support for up to four thermocouples, the PHSE-1KB helps maintain consistent board temperatures during soldering, desoldering, and component replacement processes.

Designed for Controlled PCB Rework

Preheating a PCB before rework helps reduce temperature gradients across the board, improving process control and reducing stress on components and solder joints.

The PHSE-1KB supports three operating modes to accommodate different rework requirements:

Power Mode

Operates at a fixed power level and can be used with a protection thermocouple to monitor critical areas during heating.

Temperature Mode

Maintains the PCB at a selected temperature using a regulation thermocouple, with optional protection thermocouples for additional monitoring.

Profile Mode

Controls the heating rate of the PCB through thermocouple feedback, helping keep temperatures within application-specific limits. The system supports programmable temperature profiles for repeatable rework processes.

Up to four Type K thermocouples can be connected and used across all operating modes for enhanced temperature monitoring and control.

Built-In and Custom Heating Profiles

The JBC PHSE-1KB includes three preset profile templates identified as A, B, and C. These profiles contain 2, 3, or 4 heating steps and are intended to accommodate different PCB thicknesses and layer counts.

While the built-in profiles cannot be modified, they can serve as templates when creating custom heating profiles tailored to specific applications.

Adjustable PCB Support System

The included PHSS support allows users to adjust the distance between the PCB and the heating surface. Multiple adjustment points enable secure positioning for a wide variety of board sizes and layouts.

The support offers three clearance positions:

• 28 mm (1.1")

• 50 mm (2")

• 70 mm (2.8")

This flexibility helps optimize heat application across different PCB assemblies during repair and rework operations.
