Short answer:<\/strong> Thin stamped shield frames should be quoted with packaging and deformation controls, not only flatness or coplanarity on the drawing. The RFQ should define solder feet, seating plane, tray pocket support, nesting direction, stack height, ESD need, rub protection, inspection condition, shipment photos, and whether coplanarity is checked before and after packing.<\/p>\n

A thin shield frame can leave stamping in tolerance and arrive bent if the tray pocket, stacking rule, or handling method is vague. The packaging plan is part of the functional design when solder feet, grounding tabs, clips, or thin walls must survive shipment and feeding.<\/p>\n

Treat packaging as a process control<\/h2>\n

Shield frames, EMI cans, solder-foot frames, and grounding cages often use thin material with small contact features. Bulk packing may look cheaper, but it can create lifted feet, rubbed plating, bent tabs, and poor pick-and-place behavior. If the assembly line needs trays, that cost and design should be included in the RFQ.<\/p>\n

The drawing should identify which faces may touch the tray and which faces must remain clean or free from rub marks. If the part is inspected in a fixture, decide whether the same fixture logic is used after packing. For measurement planning, use the coplanarity guide<\/a> and critical dimensions inspection plan<\/a>.<\/p>\n

Define receiving evidence before the first shipment<\/h2>\n

A deformation complaint is hard to solve if nobody photographed the first packed layer, sealed carton, pallet condition, and receiving state. For sensitive frames, ask for first-shipment packing photos and define what the buyer should photograph before unpacking. That evidence can separate production deformation from transport or warehouse damage.<\/p>\n

If parts need ESD packaging, do not let ESD bags replace mechanical support. Static protection and geometry protection are different requirements. A conductive or dissipative tray may be needed when both ESD and deformation risk matter.<\/p>\n

For export shipments, also define carton orientation, pallet stack limit, and whether a trial carton should be opened after a vibration or drop simulation. Use the packaging and shipping guide<\/a> when the route includes forwarders, consolidation warehouses, or long ocean transit.<\/p>\n
