It is important to have a high-performance cooling tract in order to guarantee optimum sol-

dering results and ensure that modules are cooled gently.

Rehm Thermal Systems offers a wide range of cooling tract variants for reflow convection

soldering with its VisionXC, which can be precisely ne-tuned to suit any production process.

The water-cooled standard solution with heat exchanger and adjustable ventilation system

works as an effective "Closed Loop" system. There are several efcient, additional options for

large and high-mass boards, primarily a bottom cooling system.

为获得最佳焊接结果以及组件得到平缓冷却，需配备高性能冷却系统。

创新型可持续液氮冷却技术

Bottom cooling makes it possible to cool high-mass boards easily and

effectively. The cold process air is blown onto the board in equal meas-

ures from above and below in order to facilitate a particularly homogene-

ous cooling process and to reduce tension in the material. It is possible

to adjust the ventilator speeds for each module. This means additional

cooling measures, such as an outfeed belt with ventilators, are unneces-

sary thanks to the low outlet temperatures. It is predominantly modules

with inhomogeneous distribution of the copper positions that will be pro-

tected against twisting and warping as a result of bottom cooling.

底部冷却系统能够可靠、高效地冷却重型PCB板：冷空气同时从上方和下方输送

到PCB板，实现均匀冷却，降低组件应力影响。每一个模块区域的风机转速都可

单独调节。底部冷却系统可以提供应用所需的超低出口温度，因此无需再使用带

风机的出口传送带等其他额外部件。此外，底部冷却系统还能够可靠保护铜层分

布不均匀的特殊组件，防止其发生扭曲和变形。

Quick Exhaust |

快速排气

Quick exhaust serves to extract process atmosphere rapidly

as a means of achieving the desired temperature change. Here

the process gas in the cooling line is extracted via the internal

exhaust system. Quick exhaust is automatically activated if

there is a change of program to a colder prole. As soon as the

temperature is within the tolerance range specied by the pro-

gram, quick exhaust is automatically deactivated. In the case

of soldering processes in a nitrogen atmosphere the desired

residual oxygen value must then be reset by adding nitrogen.

Optimised Process Changeover

Rapid switch to lower temperature proles

Process changes often need to take place during a production shift, where the reow soldering

system requires longer periods to cool from a higher to a lower temperature prole. This is the case

for example when changing from lead-free to leaded solders. For considerably quicker cooling Rehm

offers various options which enable drastic reductions in waiting times.

在生产换线时通常需要对生产制程设置进行更改。从较高的温度曲线切换到较低的温度曲线时，系统需要的冷却时间

较长，例如从无铅焊接转换到有铅焊接。为了更快冷却，锐德提供了多种选件以缩短等待时间。

Option

优化制程切换快速切换至更低温度曲线

快速排气选项可快速抽出制程气体，达到所需温度变换。冷却管道内

的制程气体通过内部排气系统抽出。如果焊接程序切换到更低温度曲

线，则快速排气选项将自动激活，并在温度达到程序设定范围时自动

停止。在氮气焊接制程中，此时必须添加氮气以达到所需残余氧气含

量标准。

冷却模组

The VisionXC transforms the classic cooling tract into a two or four-layer system, cooling Cell length 350 mm and recirculation

90°crosswise to transport direction.Individually adjustable ventilators in each of the zones make it possible to precisely control

the cooling process and influence the cooling gradient accordingly.

根据具体的生产线条件，VisionXS回流焊系统将冷却区分为2-4个阶段，冷却模组长度350mm和横向90

°冷风循环。

每个冷却区中的风机可单独

调节，从而精确控制冷却制程和冷却梯度。
