Mounting SIM900B onto the application platform

Use the connector SUNCAGEY BB530-06001-20R to fix the SIM900B onto the customer

platform

We recommend to use SUNCAGEY Company’s BB530-06001-20R as the board-to-board

connector. They are fully compatible each other. This high density SMT connector is designed for

parallel PCB-to-PCB applications. It is ideal to use in VCRs, notebook PCs, cordless telephones,

mobile phones, audio/visual and other telecommunications equipment where reduced size and

weight are important. Following is parameter of BB530-06001-20R. For more details, you can
