GHz BGA Socket - Direct mount, solderless

Transcription

1 GHz BGA Socket - Direct mount, solderless Features Directly mounts to target PCB (needs tooling holes) with hardware High speed, reliable Elastomer connection Minimum real estate required Compression plate distributes forces evenly Ball guide prevents over compression of elastomer Easily removable swivel socket lid Recommended torque = 0.18 in. lbs. (3 in. oz.) Description: SG-MLF-Socket Tolerances: Hole diameters ±0.0254mm [±0.001"], Pitches (from true position) ±0.0762mm [±0.003"], substrate thickness tolerance ±10%, all other tolerances ±0.127mm [±0.005"] unless stated otherwise. Materials and specifications are subject to change without notice. SHEET: 1 OF 5

2 1.250±0.125 (x4) * MLF20 pattern is not centered with respect to the socket mounting holes * **** To effectively conduct heat away from the package a thermal pad is recommended with vias spaced 1.0 to 1.2 mm pitch and a diameter of 0.3 to 0.33 mm. Ideally 1 via for every 3 leads has been shown to work well ±0.125 (x4) 0.850±0.025 (x2) Non-plated alignment hole ±0.050 (x4) Non-plated mounting hole Description: Recommended PCB Layout Target PCB Recommendations Total thickness: 1.6mm min. Plating: Gold or Solder finish PCB Pad height: Same or higher than solder mask NOTE: Steel backing plate may be required based on end user's application SHEET: 2 OF 5 SCALE: 7:1
