The ET-200ZK vacuum heating platform is designed for eutectic sintering of microwave devices, microwave assemblies and TR modules. It supports inert gas shielding, and the LCD control panel displays all process parameters clearly. The maximum heating temperature reaches 450℃. A glass viewing window with silicone rubber sealing achieves a vacuum level of 10⁻² mmHg. An air valve on the rear panel controls the optional silent rotary vane vacuum pump. A VACIOTEM-TV anti-backflow fitting is installed between the pump and the chamber to prevent vacuum oil from flowing backward.

1. Equipped with a digital electronic temperature limiter, which displays temperature and time digitally. Temperature is adjustable from ambient+5℃ up to 450℃. Timed operation ranges from 1 minute to 999 minutes, or continuous operation is available.
2. Sealed glass observation window with silicone gaskets, ultimate vacuum up to 10⁻² mmHg. Rear air valve controls the optional low-noise rotary vane vacuum pump. The VACIOTEM-TV vacuum fitting effectively prevents oil backflow.
3. Stainless steel housing with polished aluminum alloy panel for reliable vacuum sealing. Bell-shaped tempered glass cover with silicone seal isolates the heating element. It is fitted with a PT100 temperature probe, vacuum connector and exhaust valve on the rear cabinet.
4. Control panel includes main power switch, analog vacuum gauge, digital time & temperature readout, over-temperature alarm, plus parameter increment and decrement buttons with visual indicators.

1. Integrated desktop unit, which completes soldering strictly under vacuum environment with low-activity flux.
2. Atmosphere protection options: nitrogen, formic acid and other inert gases to satisfy special soldering processes.
3. 3.5-inch resistive touchscreen with auto operation mode, diagnostic mode, parameter configuration and user management. Professional software brings excellent operation experience.
4. Programmable temperature control system to edit accurate thermal process curves.
5. Chamber cover: automatic or manual opening (optional).
6. Φ70mm glass viewing window on the top lid for real-time process observation.
7. Free curve drawing function on the touch panel, which can create temperature profiles matching the actual soldering requirement.
8. Water cooling system provides ultra-fast cooling performance in the industry.
9. Four groups of online temperature sensors to accurately measure temperature uniformity across the bonding zone.
10. Multiple shielding gas selections (nitrogen, formic acid, inert gas) for special soldering requirements.
11. Maximum working temperature 450℃, fully compatible with all soft soldering processes.

Vacuum hot furnaces are divided into lead-free type and nitrogen-filled type, each with unique strengths. With rising packaging density and fine-pitch assembly technology, nitrogen atmosphere heating equipment has greatly improved soldering quality and production yield and become the mainstream development trend.

1. Reduce oxidation of electronic components.
2. Improve solder wetting performance and accelerate wetting speed.
3. Minimize solder balls and bridging defects to achieve high-quality soldering results.

High-quality soldering allows users to adopt low-activity solder paste, enhance solder joint reliability and prevent substrate discoloration. The main disadvantage is higher operating cost, which rises sharply with nitrogen consumption. Nitrogen consumption differs drastically between oxygen content of several hundred ppm and 50ppm. Currently, solder paste manufacturers are developing no-clean pastes that work well under higher oxygen levels to reduce nitrogen usage.
