PCT-1000预热器

the new pct-1000 is a programmable preheater that provides users exceptional ability to increase heat capacity with highly controlled thermal output. the preheater is ideal for aiding high thermal demand applications including lead-free, multi-layer boards and large ground planes. the pct-1000 can be used in a variety of processes including soldering, desoldering, smd rework operations and, with its added heat capacity, will provide faster production rates while lowering overall process temperatures.

with four programmable heating zones and one cooling zone, users select time and temperature targets, creating a preheat thermal profile.

the pct-1000 features an advanced heat control function where the temperature is controlled either at the heater output (internal) or at the board (external). the "external" control function uses a thermocouple which can be placed on the board or a component. the external control function enables users to heat with high levels of assurance; preventing such undesirable effects as underside component reflow, thermal shock to sensitive components and damaging peak temperatures.

pct-1000 is equipped with the highly advanced heater design found on sophisticated ok international rework syst. its convection heater creates a vortex effect that efficiently directs and concentrates heat. this, coupled with the precise feedback control and thermal profiling capability, establish the pct-1000 as a powerful, precise benchtop solution for increasing productivity.

the pct-1000 is easy-to-use with clearly marked controls. the front panel features a 20 x 4 lcd display and 3 input buttons. step by step programming makes profile creation simple and straight forward. the system stores up to 50 thermal profiles plus one default start up profile.

while the pct-1000 can be used with or without a board holder, users often need a quick and flexible way to position a board over the preheater.

the new bh-1000 board holder consists of posts and rails and is a highly flexible system. it has two sets of post-rail assemblies (two posts, one rail per assembly). two sliding clips are mounted on each rail and require minimal board-edge space to clamp the board. the post-rail assemblies can be located as close as 12 mm (1/2") to virtually any distance apart. additionally, each post-rail system can be converted to a stand-alone post-pin configuration with removal of the rails and by adding the threaded pins (shown right). these pins can be used for holding board tooling holes or for board support.
