Prototype PCB shielding cans are used in the early stages of shield production design. The purpose of these prototype samples is to validate the concept, functionality, and user experience of the product, allowing for improvements in further development and production. PCB shielding typically involves metal shield covers or frames made from tin plate or nickel silver, which are used to reduce or eliminate electromagnetic radiation generated by the equipment, or to prevent external electromagnetic waves from entering the device.

Advantages of choosing a board level shielding can prototype
- No mold cost
- Shorten the development cycle – can be completed in 2-3 days at the earliest
- Verify the prototype design – by making prototype samples, engineers can verify whether the design is effective at an early stage and make necessary adjustments.
- Reduce the minimum order quantity and start production with one
- Quickly optimize the design, quickly adjust the plan and test it – engineers can evaluate the effect of the shielding cover, determine whether it can effectively reduce electromagnetic interference, and whether further optimization of the design or material selection is needed
- Provide reliable data support and optimization of mold structure for batch production – through the production and testing of prototype samples, enterprises can better understand the manufacturing process and material cost of the shielding cover
- Prototype samples can also be used to show customers to get their feedback
What kinds of prototype samples can be made?








The materials that can be selected for prototype samples?
Tinplate – low cost, easy to process, good solderability, but the surface is easy to rust
Nickel Silver – good corrosion resistance, excellent soldering performance, smooth surface, good heat sink , high cost
Stainless steel – cannot be directly solder, needs to be used with shielding clips, good corrosion resistance, high temperature resistance
Ternary alloy – good shielding effect, high temperature resistance, stable electrical properties, excellent soldering performance, high cost
Cold rolled plate – the lowest cost, needs to be electroplated before use, not recommended
Prototype production process
Etching – high cost, high product precision, comparable to mass-produced products
Laser – medium cost, lower product precision than etching, usually used for products with less demanding requirements
Wire cutting – lowest cost and fastest, low product precision, unclean surface
Small CNC – fast, efficient, high cost, suitable for small quantities
Soft tooling – will incur some tooling costs, suitable for prototype samples with a large number of samples, and better consistency
Prototype sample product accuracy
Product precision +/-0.01mm, bending angle +/-0.10
Prototype production cycle
The fastest delivery time is 1 day – by using laser cutting and small CNC bending equipment, the delivery of prototype samples can be completed within 1 day Conventional 7-day – after cutting by etching or laser wire cutting, it is made using a simple fixture
Packaging of prototype samples
Tray packaging – can effectively protect products from shock, vibration and pollution, and prevent damage during transportation and storage
Plastic bag packaging – some larger products are packaged in simple plastic bags
Reel and Tape – prototype samples are generally not recommended to use reel and tape , which is costly and takes a long time to customize.
Packaging of prototype samples
1-20 prototype samples for simple testing
100 for testing and producing small batches of prototypes
500-3000 for small batch production without the need to open a mold
Impact of Shield Prototype Sample Cost
Product size
Material selection—The cost of using ternary alloy materials will be higher than that of nickel silver and tinplate
Structure—The folding frame structure is simpler and faster, while the stretching requires the calculation of stretching data and the cost will be higher
Quantity—The quantity will affect the cost of the product
