MR-140A
Designed for easy integration into automated equipment.
[MR-140A]
MR-140A pulsed heat controller controls pulsed current for heating to obtain ideal temperature to perform reflow soldering precisely. Real-time temperature feedback from a thermocouple attached to a thermode enables to adjust heat temperature in detail and precision performance according to the programmed heat profile can be done. MR-140A shows great performance also at ACF bonding and heat staking.
Features
-
◆Compact remote control model
The Control version consists of 2 units: one is a controller with a control screen and the other is an output transformer.
This allows you to place the transformer next to the reflow head, so it reduces output loss.
Compact design for easy integration into automated equipment. -
-
◆Large LCD
Displays both graphic and numerical data of setup values, measured values, waveforms, a schedule number and a program name all at once on a same screen.
-
◆Transformer selectable
Four types of transformers. 2kVA / 4kVA by output heating capability, and high-voltage / low-voltage by secondary voltage.
You can choose transformer to match your requirements. -
◆Preheat and Reflow Control
Preheat and Reflow Control is newly added to MR-140A.
The control will switch to the Preheat stage and Reflow stage after the temperature reaches the target temperature in addition to the conventional heating method that is given priority at setting time. -
◆IDLE HEAT and BASE TEMP
MR-140A can set wider range IDLE HEAT from 25℃ to 300℃, than previous model from 25℃ to 100℃.
-
◆A variety of thermode lineups
Thermodes which meet customers’ requirements can be offered. Please consult for a design of it.
