Process documentation, traceability & co.

The variety of MES systems on the market requires indivi-

dual adjustment of data transfer from the Rehm reflow sol-

dering system to the client’s superordinate manufacturing

management system (MES). Superordinate to this is the

ERP system, which the whole company looks at, and which

allows for logistic optimisations across all sites. However,

the MES system focuses on a company’s individual produc-

tion lines. Rehm uses an ROI interface (Rehm open inter-

face) to transfer individual data. Machine-specic operati-

onal data that is due for the respective system is collected

and passed onto the MES system as a bundle. It is possible

to ensure the seamless traceability of products, compo-

nents or batches in this way. A data set is created for every

assembly, which documents the relevant process parameter

during the run. The assembly can be clearly identied and

assigned via a barcode scan on the assembly itself, or by

scanning the batch card. Process locking is also available

as an option. Here, the scan is compared with the database

and the assembly is only transported to the system in the

event of approval. Defects can be detected and prevented in

this way and therefore lead to process improvements.

Accurate proling capability

3 steps to a prole – 5 steps with vacuum

5 steps with vacuum

A pre-vacuum doesn’t just allow the Galden

steam to be evenly

injected, it also enables solvents and moisture to be de-gassed

from the solder paste. After the max. soldering temperature has

been reached, the gases that are still present can escape from

the solder paste more easily using an end vacuum. Surface

binding of up to 99 % occurs as a result.

1. Pre-vacuum | Uniform distribution of the Galden

2. Injection of the Galden

| Pre-heating of the PCB

3. Injection of the Galden

| Ideal soldering temperature

4. Vacuum during the melting phase | Void-free solder joint

5. Exhaust of the Galden

| Cooling

This makes proling simple! With the Rehm Condenso series,

you only need three steps to create an optimum prole for your

assembly. What’s more, the possibilities are endless for further

rening and adjusting your prole, depending on your require-

ments. However, the following steps are usually enough to

reach the optimum temperature prole for your application:

1. Injection of the Galden

| Pre-heating of the PCB

2. Injection of the Galden

| Ideal soldering temperature

3. Exhaust of Galden

| Cooling

The WPS 2.4 is a brand-new, wireless measuring system

which is used to continuously control the temperature

prole. It consists of a sensor with antennas, as well as a

wireless and evaluation unit. The temperature sensor is

directly attached to the workpiece carrier. It works passively

and doesn’t require an external energy supply. A complete

soldering prole can be determined and transferred to the

system software in real-time, without any annoying cables

or batteries. Software-aided documentation and evaluation

functions (Rehm Recorder) allows for a new, complete

traceability level.

Connection to a superordinate Manufacturing Management System (MES)

All Condenso systems are tted with the Rehm

recorder. The documentation tool replaces exter-

nal temperature recorders and records relevant

process data such as temperature and pressure.

Data collection and traceability are carried out

at an unprecedented level – without having to

interrupt production. This is how soldering proles

are accurately recorded and can be called up and

reproduced every time by series production. The

measured values can be shown graphically with

the Rehm recorder and can therefore also be

documented and compared.
