MECHANI CAL PROBLEMS (0)

Socket : wit h microst rip, same t echnology as previous (FPPA) package EDQUAD 52 pins ASAT

New problems with Aries socket and ASAT TQFP100 package

  • The socket was t est ed wit h At lant ic package at ARI ES house :

Some devices present an excess of plast ic in t he corners Some small chips goes under t he microst rip : no elect rical cont act , t he MGPA does not work ! Microst rips could be t wist ed due t o t his small chips, t he MGPA does not work !

NO problems

Solutions

  • Very caref ully clean up t he PCB and t he socket

PARAMETER MEASUREMENTS TO BE DONE DC power supply

Current

I2C register

Internal Default Value (64) after reset

Scan Chain Functionality

Put some logic input to several values and clock them

Offset Current Generation I2C register 3 I2C values must be tested

Base line on 3 differentials gains amplifiers

Calibration Pulse Generator 3 I2C values which represents 3 different charge injection

(with lookup table values) Output amplitude on 3 differentials gains amplifiers

Qin = 4.5 pC

Rise and Fall Time and peak amplitude on G12 differential gain amplifier

Qin = 8 pC

Rise and Fall Time and peak amplitude on G6 differential gain amplifier

Qin = 50 pC

Rise and Fall Time and peak amplitude on G1 differential gain amplifier

Noise
