MEMS Devices
DIE Attachment
High Power LED
Hybrid Assembly
Flip Chip
Package Sealing

Feature of the vacuum reflow oven:

1. Soldering temperature: the maximum soldering temperature of HV3 vacuum eutectic furnace is ≥ 500 ºC.

2. Vacuum degree: limit vacuum degree ≤ 10-6 PA working vacuum: 10-4 PA.

3. Effective welding area: ≥ 260mm * 240mm

4. Furnace height: ≥ 100mm, customized for special height.

5. Heating method: infrared heating at the bottom + infrared heating at the top. The heating plate adopts semiconductor silicon carbide graphite platform. It is not easy to deform after long-time use, and has high thermal conductivity, making the surface temperature of the heating plate more uniform.

6. Temperature uniformity: within the effective soldering area ≤± 2%.

7. Heating ramp:120 ºC / minute.

8.Cooling ramp: 60-120 ºC / minute (the ramp of no-load, temperature cooling from 100 ºC).

9. Meet the soldering requirements of soldering materials temperature≤ 500 ºC.

For example: In97Ag3, In52Sn48, Au80Sn20, SAC305, Sn90Sb10, Sn63Pb37, Sn62Pb36Ag2 and other preforms (can be soldered without flux eutectic), solder paste of various components, and curing of materials below 500 degrees.
10. Soldering void rate: After a large number of customer verification, when HV3 vacuum eutectic furnace solder with soft solder,  the void rate can be controlled between 0-3%.
