| Where to get EMC/EMI Metalic PCB Shield? |
| (1/5) > >> |
| Mechatrommer:
as the topic states... i'm talking about very small shield like 25 x 10 x 5 mm dimension that i can put a pcb inside, anybody who own (or dismantle) Tek active probe P6245 et al will know this. apart from the normal larger shield that is soldered or clipped on to the pcb. anyone know good suppliers? i found hollandshielding.com but few reasons that i hate: 1) they only show larger shield 2) no clear price tag for estimation of my product 3) we need to send email and the file and wait for their reply with quotation 4) i'm not sure if they can work internationally to remote place like here. |

EMC/EMI shields are just grounded metal covering the sensitive component .So really any metallic project box fitting those dimensions would work as long as it's grounded. |

Wurth or Harwin might do something close. |

What kind of volumes? For one-offs, it might be easier to get a shielding case milled out and screw it to the PCB, or try to use a standard size one like from Laird, Leader Tech, etc; see https://www.digikey.com/products/en/rf-if-and-rfid/rf-shields/867 (14R-CBSA-0.5X1.0X0.13 looks close). For larger runs, shops like Fotofab can build to order. |
