>> RK is Reflow Korea
RK Series reflow equipment is optimized and developed for “Lab. Small & Multi” reflow soldering work. As a representative European equipment among small reflow equipment, a company was established in 1972 and manufactures various SMD assembly equipment other than reflow. NamA Electronic provides RK series reflow to Asian region.
The RK Series is a vertical convection circulation method of full hot air convection equipment, which has good temperature and air flow efficiency and is capable of reflow soldering in a “lower temperature” state. This reflow is designed with simple and easy operation method so that anyone can use the equipment easily.
This equipment was selected as a low-carbon reflow equipment. RK31 model is a low power consumption reflow that can use single-phase power from a 220V single phase. This low-power equipment does not require equipment installation space and power boost.
It has a real-time temperature profile measurement function and shows the measured Soak – Melting – Reflow temperature section on the automatic calculation screen, making it more efficient. It is a desk top equipment that can realize high-quality reflow soldering work.
>> The measured temperature data is displayed on the real-time screen and can be saved as Excel data through the USB port.
>> The profile file is saved as Excel format, and reflow soldering environment analysis management and application are possible in PC environment.
>> These functions are contributing a lot to Lab, QC, and industry-university-research center work.
USE : Lab, QC, and industry-university-research center, Component development, small and multi product, LED, Curing, Rework, Paint dry, Soldering Test, LED, module, etc.

RK Series Reflow has 3 types of reflows, RK31/41/51. It is classified by the number of heating zone. As 4.0 industry environment product, it is a reflow that can apply data about the reflow environment through USB and RS-232. By control conveyor speed and temperature, it can be used as a curing system.
Desk top reflow / under cabinet (Opt)
Reflow machine has three seperated heating zones(Preheating+ Soak + Reflow) and one cooling area. It adoptes vertical Full Hot Air Convection method and the special glass cover helps real-time inspection work. Chamber lighting unit can be selected (op).
RK31 has spring belt system(Mesh-op). This spring belt is finger conveyor method. it is a small reflow equipment wider quality evaluation of semiconductors, precision parts, and R&D in a method that does not vibrate or shake or fine vibration than the finger conveyor method.
It is a machine that can measure, store and analyze temperature, and it saves data as an Excel file and analyzes it in a PC environment.

Vertical Hot Air Convection Method
RK reflow is a vertical convection method, and it is an equipment that can realize stable reflow soldering by minimizing the shaking of FPCB or light-weight SMD parts by using a hot air flow method from the bottom. Convection heating provides “No shadowing”& No hot spots.
RK31 reflow adopts Spring (Mesh-op) Conveyor method and it works up to a PCB Max width of 260mm. RK31’s Top Window method provides the inside of the chamber monitoring. With special high-insulation material, it maintains the internal temperature of the equipment stably and is designed to prevent heat loss in the chamber.
RK31’s Hot Air Convection is a vertical convection method, and it is an equipment capable of realizing high-quality reflow soldering of BGA, uBGA, PLCC, under-ball.
Excellent quick preservation and recovery against heat loss
Both sides of the chamber are designed with quadruple insulation, and it is an integrated chamber method without heat loss between the door and upper/lower joints of the door and chamber by vertical convection airflow, so there is no heat loss or heat shadow phenomenon.
It is an eco-friendly equipment that has excellent thermal resilience with an all-in-one chamber method and consumes very little power, and reflows at a much lower temperature than the IR system using recirculated hot air.
