Preheat Tool Reduces Warpage Risk
March 22, 2007 |Estimated reading time: Less than a minute
GARDEN GROVE, Calif. The focus preheater PCT-100 convection tool from OK International ramps to a desired preheat temperature and provide stability during hand assembly or rework operations on surface mount components. The system can also be used with thru-hole devices. Stable preheat temperatures can reduce the risk of board and component warpage due to thermal stresses.
Convection-air heating maximizes responsiveness and prevents temperature over-shoot, according to the company. The product, used with or without the optional board holder, uses a controlled temperature slope to ramp to appropriate temperatures for tin/lead or lead-free rework. The ramp reportedly is faster than other models, without thermal shock to the board or components. The unit incorporates an attached fan to reduce heating and cooling cycle times.
Designed for various production environments, the PCT-100 maintains low levels of audible noise, and meets standards for maximum case temperature. It also carries CE and other international certifications for operator safety and system performance.
