Circuits Assembly Online Magazine - OK Int’l Develops Hand-Held Convection Tool

HCT-900 Hand Held Convection Tool is a low-cost rework system with the flexibility to handle a range of thermally demanding production and rework applications, including Pb-free. Typical applications for the 300W unit include removal or replacement of QFPs, PLCCs, SOPs and TSOP devices. It can also provide heating and reflow for touch-up work as well as heat shrink and other local heating applications.

Closed-loop thermocouple feedback regulates output temperatures, and control temperatures can be set in the range 100º to 500ºC. The user sets the heat and airflow control dials to the required values for the application. Unit maintains the required temperature automatically, even if airflow is adjusted.

The low-noise pump (less than 45 db) provides precision airflow control. A power-off, cool-down function retains the airflow as the unit powers down for efficient heater cooling and reduction of thermal stress.

A range of nozzles are available for general purpose applications or specific SO and TSOP packages, or PLCC, BQFP and QFP devices. Also accepts many industry standard nozzles.

Three versions are available to suit input voltages of 115VAC (HCT-900-11), 230VAC (HCT-900-21) or 100VAC (HCT-900-10).
