The CTS Perspective is a new regular column from the engineers at cts Group, exploring how industry really automates and digitalises – one practical insight at a time.
In modern electronics manufacturing, significant attention is given to machine performance, automation and production speed. However, one often overlooked factor has an equally important impact on efficiency and production stability: where materials are positioned throughout the manufacturing process.
Whether handling SMT reels, trays, KLTs or PCB magazines, the location of material carriers directly affects productivity, traceability, line continuity and operator efficiency. Poor material placement creates unnecessary movement, confusion and delays, while a structured material flow supports a stable and scalable production environment.
The Challenge: Too Early, Too Late, or Simply in the Wrong Place
One of the most common problems in electronics manufacturing is material arriving at the wrong location or at the wrong time.
When material is delivered to the line too early, valuable production space becomes overcrowded. Operators are forced to work around excess inventory, visibility is reduced and the likelihood of material mix-ups increases. In many factories, this gradually creates hidden inefficiencies that are accepted as “normal” daily operations.
Conversely, delivering material too late has a direct impact on production output. Lines stop, operators wait for replenishment and urgent manual interventions disrupt the wider logistics process.
The most damaging situation, however, is when material exists within the factory but is not where the process expects it to be. Inventory systems may show available stock, yet production still stops because operators cannot locate the correct carrier quickly enough. This leads to unnecessary search times, picking errors, incorrect returns and loss of process control.
A Structured Approach to Material Placement
Effective material placement should be based on three key principles:
- Response Time – How quickly is the material required by production?
- Process Stability – Does material need to remain close to the line for operational continuity?
- Protection Requirements – Does the material require controlled handling such as ESD, MSD or climate protection?
These factors determine whether material should be positioned directly at the production line, within a controlled buffer area, or inside structured storage systems.
Different carrier types also influence placement strategy. SMT reels, for example, are highly dynamic and frequently accessed, making organised storage and rapid retrieval essential. PCB magazines may need to remain near the line but not directly at the machine, while trays and KLTs are often better suited to defined storage or transfer locations.
The Importance of Integrated Material Flow
Material placement alone is not enough. Transport systems and process control must work together seamlessly.
AMRs, manual milk runs and warehouse systems only deliver maximum value when transfer points, return locations and carrier status are clearly defined. Without this structure, material quickly falls into operational “grey zones” where stock is technically available but not properly assigned within the process.
Successful intralogistics therefore requires close integration between MES/ERP systems, storage solutions, transport management and line-side operations.
Conclusion
Material placement is not simply a storage decision — it is a core part of manufacturing strategy.
Factories that systematically align storage, buffering and line-side delivery with real production requirements achieve greater process stability, improved traceability, reduced operator movement and fewer production interruptions.
At cts, intralogistics solutions are designed around these real-world operational challenges. By combining intelligent storage architecture, transport integration and process-driven material flow, manufacturers can create scalable production environments that support efficiency, flexibility and long-term growth.
