UF-2000A / UF-4000A / UF-R4000A Power Supply (formerly known as UNIFLOW4, UNIFLOW 4R)
UF-2000A / UF-4000A / UF-R4000A is a new power supply for Hot Bar Reflow Soldering, Heat-Sealing, ACF Laminating and Heat Staking technologies. It utilises pulsed heat technology to provide targeted heating and precision temperature control for a variety of components including flex circuits, ribbon cables, wires, SMT components, single or dual-sided edge connectors and thermo-compression bonding of gold ribbon.
Key Features UF-2000A / UF-4000A / UF-R4000A Power Supply
- Closed-loop temperature and time control
- Stores 63 heating profiles
- Remote programming via RS-232/485
- Two thermocouples for process control and auxiliary monitoring
- Comprehensive and informative user interface: (Graphic and numeric process data, Status and alarm messages, Heat profile setting and envelope limits, Temperature error indicators, User scalable time axis, Real time temperature plot)
- Choice of a standard unit with built-in transformer or remote unit with small control unit and remote transformer. There are four versions of the remote transformers with a choice of two energy levels and two thermode voltage ranges for additional application flexibility
