.1373.2756.1373 TGA94-HM Assembly Notes 1. Clean the board or module with alcohol. Allow it to dry fully. 2. Apply solder paste to each pin of the TGA94-HM, and heat achieve reflow, being careful not to exceed the thermal budget. 3. Clean the assembly with alcohol. 4. To attain quoted RF performance, the following is required: i. On the printed circuit board, there must be two 1mm (.394 ) diameter openings on the backside (RF Ground Plane) of the circuit board. Location of the openings is contained in the Q Evaluation Board layout. The 1 mm diameter openings for the board are shown in the diagram below in reference to the base of the package. ii. Use of a carrier plate with 2 mm (.787 ) diameter holes. The holes should be located with respect to the package pin-out as shown in the diagram below. The holes should be 4mm deep. 5. To improve thermal performance, the following is recommended: i. The use of a 4 mil indium shim between the circuit board and the carrier plate. ii. The In shim should have the same hole diameter and positioning as the carrier plate (see diagram below for location with respect to the package backside).the holes should be machined fully through the In shim..2756 1 18.3 Location of.787 diameter holes for carriers.2146.197 Location of.394 diameter openings for circuit boards.8 7 12 \ Rev.
