MOUNTING RECOMMENDATIONS General LDMOS Tbase station modules are manufactured with the dies directly mounted onto a copper flange. The matching and bias circuit components are mounted on a printed-circuit board (PCB), which is also soldered onto the copper flange. The dies and the PCB are encapsulated in a plastic cap, and pins extending from the module provide a means of electrical connection. This construction allows the module to withstand a limited amount of flexing, although bending of the module is to be avoided as much as possible. Mechanical stress can occur if the bottom surface of the module and the surface of the amplifier casing (external heatsink) are not mutually flat. This, therefore, should be a consideration when mounting the module in the amplifier. Another cause of mechanical stress can arise from thermal mismatch after soldering of the pins. Precautions should be taken during soldering, and efforts made to ensure a good thermal contact between the flange and the external heatsink. External heatsink (amplifier casing) The module should always be mounted on a heatsink with a low thermal resistance to keep the module temperature as low as possible. The mounting area of the heatsink should be flat and free from burrs and loose particles. We recommend a flatness for the mounting area of between 50 m concave and 50 m convex. The 50 m concave value is to ensure optimal thermal behaviour, while the 50 m convex value is intended to limit mechanical stress due to bending. In order to ensure optimum thermal behaviour, the use of thermal compound is recommended when mounting the module onto the amplifier external heatsink. The following recommended thermal compounds have a thermal conductivity of >0.5 W/mK: * WPS II (silicone-free) from Austerlitz-Electronics * Comp. Trans. from KF * 340 from Dow Corning * Trans-Heat from E. Friis-Mikkelsen. The use of thermal pads instead of thermal compound is not recommended as the pads may not maintain a uniform flatness over a period of time. Mounting PREPARATION Ensure that the surface finishes are free from burrs, dirt and grease. 2004 Oct 11 6 CAUTION
BGF1901-10
During the following procedures ESD precautions should be taken to protect the device from electrostatic damage. PROCEDURE 1. Apply a thin, evenly spread layer of thermal compound to the module flange bottom surface. Excessive use of thermal compound may result in increased thermal resistance and possible bending of the of the flange. Too little thermal compound will result in an increase in thermal resistance. 2. Take care that there is some space between the cap and the PCB. Bring the module into contact with the external heatsink casing, ensuring that there is sufficient space for any excess thermal compound to escape. 3. Carefully align the module with the heatsink casing mounting holes, and secure with two 3 mm bolts and two flat washers. Initially tighten the bolts to "finger tight" (approximately 0.05 Nm). Using a torque wrench, tighten each bolt in alternating steps to a final torque of 0.4 Nm. 4. After the module is secured to the casing, the module leads may be soldered to the PCB. The leads are for electrical connection only, and should not be used to support the module at any time in the assembly process. A soldering iron may be used up to a temperature of 250 C for a maximum of 10 seconds. Avoid contact between the soldering iron and the plastic cap. Electrical connections The main ground path of all modules is via the flange. It is therefore important that the flange is well grounded and that return paths are kept as short as possible. An incorrectly grounded flange can result in a loss of output power or oscillation. The RF input and output of the module are designed for 50 connections. Incoming inspection When incoming inspection is performed, use a properly designed test fixture to avoid excessive mechanical stress and to ensure optimal RF performance. Philips can deliver dedicated test fixtures on request.
