A cardboard divider can separate electronic components without demonstrating protection against electrostatic discharge. For an ESD-sensitive item, the responsible product team must specify the required protective properties and system. Develop the mechanical packing around that approved configuration, using evidence and checks appropriate to each function.<\/p>\n

Separate two technical requirements<\/h2>\n

Mechanical protection addresses movement, impact and contact between items. Electrostatic protection addresses a different risk, linked to the component and its handling environment. A mechanically intact pack may lack the required ESD properties. Equally, individually approved ESD packaging may still need support to prevent damaging movement inside the outer box.<\/p>\n

The EOS\/ESD Association describes standards covering packaging materials and ESD control programmes<\/a>. These properties require specification and verification. Board colour, a broad marketing description or the absence of visible damage is not sufficient evidence that the complete arrangement meets the needs of your component.<\/p>\n

Have the ESD configuration defined by its owner<\/h2>\n

Identify the components concerned and the environments in which they are handled. Map preparation, closure of individual protection, storage, transport, opening and use at the destination. The protective approach needs to remain coherent across those stages. Packaging suitable for one part of the process may require different precautions at another.<\/p>\n

The technical file should state the required properties, supporting documents and responsible approver. Avoid giving a divider manufacturer only a vague instruction such as antistatic cardboard. Different participants may interpret it differently. Have the competent team define the requirements, applicable references and verification methods so that purchasing, packaging and production share the same meaning.<\/p>\n

Measure the component with its individual protection<\/h2>\n

Size the cell for the product as it will enter the box. A bag, cap or connector cover changes dimensions and contact surfaces. Include bag closures and projections that must not be pinched. Check removal too: a well-fitted component should not have its individual protection pulled or torn when an operator takes it out.<\/p>\n

In a hypothetical example, a circuit board is placed inside approved individual packaging before entering a divider cell. If the cell opening was specified around the bare board, the bag may fold or catch during loading. Removing the bag locally is not an appropriate fit correction. Review the cell and handling method while preserving the configuration approved by the ESD owner.<\/p>\n

Identify mechanically sensitive features<\/h2>\n

Show connectors, pins, raised components and gripping areas on the drawing. State where support is permitted. A divider wall should not unintentionally bear against a pin or fragile feature. For a family of products, review the projections unique to each version before authorising common packaging.<\/p>\n

Estic-Maillot partitions<\/a> include electrical and electronic component applications. This describes an application family; it is not an ESD certification for every board offered. Confirm the proposed material and supply scope, then relate them to the complete protective system agreed for your product.<\/p>\n

Ask for evidence tied to the supplied reference<\/h2>\n

Documents should correspond to the material and version actually purchased. Check reference identification, declared properties, methods and stated limitations. If a property depends on a treatment or particular component, ensure it appears in the approved bill of materials. Evidence for a different grade should not be transferred by analogy merely because the materials look similar.<\/p>\n

Keep the documents with the packing specification and define change control. A supplier substitution, different surface or new individual protective component may need another assessment. Purchasing should know which characteristics can change freely and which require technical approval. This is more reliable than attempting to recover the reasoning after an unexpected delivery arrives.<\/p>\n

Observe the packing station<\/h2>\n

Trial loading without opening or modifying protection that must remain in place. Check gripping, orientation and access for removal. Instructions should state who may intervene on the individual packaging and under what conditions. An improvised correction outside the intended environment can undermine the protective approach even if it makes the part fit more easily.<\/p>\n

Include returns and packages opened for inspection. Receiving checks should distinguish damaged individual protection, the wrong reference and a purely mechanical divider defect. Keeping those categories separate helps teams decide the appropriate next step rather than returning an altered configuration to normal use without review.<\/p>\n

Coordinate the evidence for both functions<\/h2>\n

Mechanical and electrostatic requirements can be managed within one project without being merged into one unsupported claim. Use a responsibility table identifying the owner of each requirement, its evidence and the approved configuration. The packaging designer can then address fit and support while the ESD team confirms the necessary protective properties.<\/p>\n

If a trial changes the bag, board or handling sequence, identify which requirements might be affected. A successful mechanical result does not automatically approve the ESD change, and an accepted ESD material does not prove transport protection. Both decisions should remain traceable to the complete version intended for production.<\/p>\n
