With a linear prole, the component is not heated in a
stepped manner during soldering, in fact it is heated
along an identical linear temperature gradient. Linear
proles can reduce cycle times and can help to reduce
soldering errors such as tombstoning.
使用线型加热曲线时，组件不是以阶梯式加热，而是沿几乎
完全相同的温度斜率加热。线型温度曲线可以缩短循环时
间，消除元件立碑等焊接错误。
The component is brought to a temperature of at least
240 °C for soldering. Using a saddle prole the board
is gradually heated in line with pre-dened, individual
temperature ranges. Even components with differing
thermal masses are heated homogeneously and tem-
perature differences minimised.
组件被加热至240°C进行焊接。在马鞍型温度曲线下，PCB板
将逐渐加热到预定义温度范围。即使拥有不同热质量的组件
也能得到均匀加热，最大限度降低温差。

The centrepiece of our VisionXC is the stainless steel process chamber with
its outstanding heat transfer owing to advanced hole nozzle geometry as
well as monitored adjustable overpressure in the heating module, guaran-
teeing homogeneous and gapless heat transfer to the circuit board. The
inert process atmosphere can be assured throughout the entire soldering
process and beyond because the closed system ensures that no external
air nds its way into the process chamber. The heat flow within the system
takes place by means of circulation, i.e. the process gas of the preheating,
peak and cooling zones is extracted, cleaned and reinserted into the pro-
cess at the sides.

A Clean Machine:
Effective Residue Management
As is the case with all industrial processes, substances are generated during
SMT production which have to be removed from the process cycle because
they contaminate the system. Our highly effective residue management
function puries the process gas safely and reliably, and keeps your system
clean and dry.
清洁型解决方案：
高效的残渣管理
和所有工业制程一样，SMT生产线同样也会产生可能污染系统的残渣，因此必须及时将
残渣从制程循环中排出。我们的高效残渣管理系统可以安全、可靠的净化制程气体，保
持系统洁净、干燥。

Liquid residues condense above all on the cooling
tract’s lter units, by which they are then removed.
The system is easy to clean. The lters are ex-
changed in sets at the back of the system. The
process chamber doesn’t even have to be opened.
Optional 7 stages for max efciency, Filters up to
98% increase process safety.
液体残留物首先在冷却区单元内冷凝过滤，然后被排
出。过滤单元易于清洁，过滤器可以通过系统背部直接
更换而无需打开炉膛。可选配七段过滤，最高过滤效率
高达98%。
