Inline Formic Acid High-Vacuum Sintering Furnace — VX410

The furnace consists of 5 zones: Loading Zone, Preheating Zone, Heating Zone, Cooling Zone and Unloading Zone. It is configured with a double-layer vacuum chamber (internal and external), a distinctive design compared with single-layer vacuum chambers of similar equipment. The double-layer structure ensures zero workpiece oxidation and formic acid leakage prevention, with the oxygen content maintained below 5 ppm. Programmable Multi-Stage Vacuum Pumping The furnace features programmable 3–5 stage vacuum pumping, enabling precise control of the pumping rate and stable maintenance of the set vacuum value for optimal soldering quality. Rapid Vacuum Pumping Each vacuum pump is equipped with an auxiliary vacuum tank, which effectively shortens the pumping time of each zone, ensuring faster and more controllable vacuum pumping. Working vacuum level: 20 Pa. Precision Conveying & Positioning High-precision sensors ensure accurate conveyance of each workpiece to the designated position. In addition, each zone is fitted with a set of blocking mechanisms to prevent the fixture from exceeding the specified stroke. Dual Heating System Design Independent temperature control is adopted for the top and bottom heating modules, which effectively improves poor soldering caused by the unevenness of the module base plate. Real-Time Temperature Monitoring with 6 Measuring Points per Zone The Preheating, Heating and Cooling Zones are equipped with 6 temperature measuring points each, with a total of 18 channels for real-time monitoring of the heating plate temperature uniformity. The furnace will trigger an immediate alarm if the temperature difference exceeds the set value. The real-time temperature uniformity monitoring during soldering is realized through the 6-channel temperature measurement and alarm system for each zone, ensuring consistent product soldering quality. This furnace is independently developed with core independent intellectual property rights, free from the risk of intellectual property infringement. Core Advantages A. Only one layer of fixture is placed between the module and the heating plate, resulting in superior temperature uniformity compared with similar products (≤±2℃). B. Heating tubes can be replaced without stopping the furnace, enabling convenient maintenance. C. Long-term temperature uniformity is guaranteed; the temperature uniformity of the heating plate can be adjusted by replacing heating tubes with different power ratings during long-term operation. D. Dual safety design ensures 100% accurate delivery of workpieces to each vacuum chamber, achieving a high yield rate in mass production and effectively reducing customer costs. E. The Preheating and Heating Zones adopt heating plates with a graphite silicon carbide coating and heat conduction blocks, ensuring excellent temperature uniformity.
