Features：

1、Heller Industries provides optimized cycle (average 30s~60s) to achieve super high UPH.

2、Heller vacuum assisted reflow applies multi-zones to meet various thermal profile requirements.

3、Heller Industries utilizes advanced pumping package with high capacity for fast pump down time.

4、Reflow time under vacuum of 15 seconds was able to achieve ＜1% total void area spec.

5、Heller adopts high efficient flux collection system to collect the flux and keep tunnel clean.

6、On-the-fly maintenance is available.

7、Chamber exhaust fore line, ball valve, butterfly valve and dry vacuum pump are heated to 150℃ to eliminate flux condensation.
