From transparency to efficiency
Many customers expect the manufacturer to consistently identify and track the manufactured products throughout the supply chain and down to its individual components. In case of defects, possible sources of error must quickly be limited and a targeted recall of products undertaken. Traceability is still seen primarily in terms of risk protection. The systematic collection of process and product data, however, opens up new opportunities. The risk of running production processes with incorrect parameters or not recognising long-term temperature fluctuations in the system is minimised. The information obtained can also be used to optimise the utilisation of production capacity, better calculate material stocks, monitor production parameters and guarantee process safety.
Modern software tools make this desired transparency possible and the complete production process becomes accountable down to the smallest detail. In addition, companies can optimise their processes, from goods receipt to goods issue, and significantly increase production efficiency.
Optimum process tracking requires products or series to be clearly identified from the very first step. For this purpose, each circuit board is provided with a unique identifier, such as a serial number, which is recorded on a bar code. With a barcode connection, a scanner is mounted on the conveyor belt in front of the system and connected to the system’s PC. This allows product information, such as the order or board size to be assigned to particular circuit board, or circuit board series.
Process tracking with SAFI
Rehm has a reliable solution for optimum product and process tracking. The SAFI program documents important product parameters and machine settings during the soldering process, including on which line the board was soldered, under what conditions, with which materials, by which employees and with what result. The main focus here, for example, is the temperature profile, which can be stored, making it possible to reproduce best soldering results. In addition, information on the components and the materials used, such as solder paste, quantities and throughput times, is also stored. Errors are identified early on and manufacturing processes are optimised on a long-term basis.
The detailed overview of the entire material flow also allows eco-conscious production, since material stocks are adjusted, resources saved and downtime due to lack of material availability avoided.
The locking process offers an additional way to prevent errors. The circuit board is checked before it is fed into the system. The inserted board is only unlocked and fed into the oven if it corresponds to the currently loaded profile. Any mismatch between the circuit board and the program triggers an alarm and blocks further processing. Process locking thus prevents the production of errors and the further processing of faulty parts.
Master computer interface
Rehm Thermal Systems cooperates with various manufacturers of control systems and provides interfaces for different control systems. This facilitates the detailed collection of data, continuous matching of all features and comprehensive monitoring of processes in a centralised and coordinated manner. This intelligent software helps Rehm succeed in efficiently and sustainably controlling manufacturing processes and ensuring the highest level of quality.
