F4BME265 High Frequency PCB DK2.65 PTFE Double Sided With OSP and Green Mask

(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)

Brief Introduction

The PCB we discussed today has a size of 89mm x 61mm, with just 1 piece in a panel. It's a double sided PCB, meaning it has two conductive layers for circuitry. There are no surface mount components on this PCB. Instead, it has through hole components. The layer stackup consists of copper layers with a finished thickness of 35um (equivalent to 1oz). In between, there is F4BME265 material with a thickness of 1.5mm, and then another copper layer of the same 35um (1oz) thickness on the other side after its plating.

Here’s more details in the table.

F4BME High Frequency Laminates

F4BME series laminates are made by scientifically formulating and strictly pressing a combination of fiberglass cloth, polytetrafluoroethylene resin, and polytetrafluoroethylene film. Its electrical performance is improved compared to F4B, mainly due to a wider range of dielectric constants, lower dielectric loss, increased insulation resistance, and improved stability. It can replace similar foreign products.

Product Features

◆ DK2.17 ～ 3.0 is optional, and DK can be customized

◆ Low loss

◆ F4BME with RTF copper foil has excellent PIM index

◆ Diversified size and cost saving

◆ Irradiation resistance and low exhaust

◆ Commercialization, mass production and high cost performance

Typical Applications

◆ Microwave, RF, radar

◆ Phase shifter, passive components

◆ Power divider, coupler and combiner

◆ Feed network, phased array antenna

◆ Satellite communication, base station antenna
