PS module is as follows v 60 C for 8 to 12 hours Once baked the module s floor life will be reset and has additional 72 hours in normal factory condition to undergo solder reflow process A Please limit the number of times the GPS modules undergoes baking processes as repeated baking process has an effect of reducing the wetting effectiveness of the SMD pad contacts This applies to all SMT devices A Oxidation Risk Baking SMD packages may cause oxidation and or intermetallic growth of the terminations which if excessive can result in solderability problems during board assembly The temperature and time for baking SMD packages are therefore limited by solderability considerations The cumulative bake time at a temperature greater than 90 C and up to 125 C shall not exceed 96 hours Bake temperatures higher than 125 C are not allowed This document is the exclusive property of GlobalTop Tech Inc and should not be distributed reproduced into any other format without prior permission of GlobalTop Tech Inc Specifications subject to change without prior notice Copyright 2011 GlobalTop Technology Inc All Rights Reserved 30 riie 3 GlobalTop Technology Document 3 1 LadyBird 3 Data Sheet Tape Reel Ver VOF Gioba ro 5 5 ESD Handling A Please carefully follow the following precautions to prevent severe damage to p A GPS modules GlobalTop GPS modules are sensitive to electrostatic discharges and th
