What compact mounting parts do in an electronic assembly
Review this component together with its mating parts and delivered condition. The interfaces below define the drawing information needed to assess forming, finishing and inspection.
The reference includes round and slotted forms whose function must be identified on the assembly drawing.
Primary locating axis, face and secondary-opening interfaces
Define the primary locating axis or face before specifying the secondary openings.
Clearly distinguish holes used for attachment from those used for alignment or clearance.
Why identify a primary locating feature first?
A compact component may have several holes and projections without all of them locating the assembly.
Naming the primary axis or face gives the secondary features a consistent reference.
It also helps distinguish an alignment requirement from a simple clearance requirement.
MIM versus machining for integrated small features
Compare MIM for integrated small features with machining for straightforward turned or milled shapes.
Plan final operations where mounting interfaces require tighter control.
The proposed route is confirmed for your drawing, material and quantity. An image does not establish a fixed tolerance or a complete process specification.
Compare manufacturing capabilities →Mounting-part base material and finish requirements
Define base material, final condition and cosmetic finish separately.
Identify visible faces, permitted edge rounding and the dimensions that must be met after finishing.
Any magnetic, electrical or acoustic requirement needs its own specification.
Review material-selection information →Datum relationships, opening positions and enclosure-fit checks
Inspect datum relationships, opening positions and the final fit inside the enclosure.
State any magnetic, electrical or cosmetic requirements explicitly.
Specify the drawing revision and the condition in which each dimension is inspected. Record the agreed dimensional and functional checks before sample approval.
Quality documentation →Prepare a Product-Specific RFQ
- Component definition. Send the 2D drawing and 3D model, where available, with the drawing revision and the requested part or assembly scope.
- Mating information. Include the assembly references needed to define the interfaces discussed above.
- Delivered condition. State material, finishing and inspection requirements, identifying any items that need a manufacturing recommendation.
- Supply plan. Include sample needs, expected order and annual quantities, packaging requirements and target timing.
Product Questions
Can a metal mounting part also serve an electrical function?
Possibly, but conductivity, grounding or shielding requirements must be specified and verified rather than inferred from the material appearance.

How are appearance and functional fit checked?
Inspect datum relationships, opening positions and the final fit inside the enclosure. State any magnetic, electrical or cosmetic requirements explicitly.
Technical Context
The product-specific notes above identify drawing-review questions. General process and material references are collected separately; they do not verify a material grade, production qualification or performance claim for the pictured part.
