Top lead free reflow oven with 8 heating zones
1. The brand computer and Siemens PLC intelligent control system, high precision temperature control is ± 1-2 ℃ (if the computer crash accident, it can realize off-line work, do not affect production) and to ensure that the control system is stable and reliable;
2. Windows XP operating interface with powerful and simple operation.
3.In order to ensure safety and reliability, the cylinder body can be lift up automatically.
4. Device is equipped with mesh belt, transport smoothly, no shaking and no deformation, which ensure smooth PCB transport. Synchronous guide transmission mechanism and automatic SMT machine online connection ensure that guide adjustable wide precision and high service life.
5. Automatic control lubrication system and automatic lubrication transmission chain.
6.All heating zone control by computer PID(upper temperature zone and lower temperature zone implementation independent temperature control, that means it can divide temperature area heat, in order to reduce starting power)
7. Net/chain transmission by computer to carry out the whole closed loop control, which can meet different kinds of PCB production at the same time.
8. With fault sound and light alarm function.
9. With leakage protector, ensure that the operating personnel and control system security.
10.The built-in UPS and automatic delay shutdown system guarantee return welder in power or overheat do not damaged PCB and the machine.
11. The German ERSA world leading microcirculation heating mode, and the upper and lower independent air microcirculation system, temperature uniformity and thermal compensation high efficiency, high efficient supercharged accelerated air duct, greatly improve the circulating hot air flow, heat up temperature quickly (about twenty minutes), thermal compensation for high efficiency, high temperature welding and curing;
12. The upper and lower every temperature zone with independent temperature inductive sensor, real-time monitoring and compensation every temperature zone balance;
13. Have password administration of the operating system, to prevent the irrelevant personnel changes to the process parameters, operation records management traceability process parameters change process, improve the management convenient. For storing user existing temperature speed setting and Settings of the temperature curve, and can be used for all data and curve printing;
14. Integrated control window, the computer switch, test curve, print curve and data transmission are easily operation, humanized design. Equipped with three-channel temperature curve online testing system, may at any time to check welding objects by the actual temperature curve (without the other match temperature curve tester);
15. From international technology quick cooling system, use a magnifying glass type efficient rapid cooling, cooling speed can reach 3.5 ~ 6 ℃/ SEC, management is very convenient; The outer forced cooling device, ensure that spot crystal effect (Option selected items, the standard configuration for forced natural air cooling).
