General Description
I-1 General
The Reflow Checker –Modular Type (RCX-1) is a system in which a heat-resistant memory unit moves
together with the object to be measured inside the conveyor furnace, measures the temperature at a
constant interval and memorizes the data, and an interface unit, when the heat-resistant memory unit is
taken out of the furnace and connected
（
Bluetooth or USB cable
）
to this unit, outputs the temperature
profile.
I-2 Features
- High thermal performance, being smaller and lighter (6 points measuremen, width 65mm)
-
Unnecessary Interface unit for the data transmission to PC.
Bluetooth enables wireless data transfer to a PC.
-

- Cooling unit cools down Memory unit rapidly.
I-3 Use environment
Memory unit is the equipment to measure the temperature by traveling in a reflow oven. Note that if the
inside of memory unit becomes very hot, IC, battery, etc. can make internal burst. When measuring, do
not allow the internal temperature to rise above 80
℃
.
Although the use environment depends on reflow ovens, we examined the test to show a guide profile,
The temperature inside memory unit was under 80
℃
in the following profile
Reflow oven with eight zones, far infrared radiation and hot air convection method.

Temperature of memory unit before it is put into furnace : Room temperature (35
℃
or lower)
(* When the inside temperature of memory unit is over 35
℃
, to protect a memory unit,
the measurement can not be performed.)
