TDA1308; TDA1308A Class-AB stereo headphone driver Rev. 04 -- 25 January 2007 Product data sheet 1. General description The TDA1308; TDA1308A is an integrated class-AB stereo headphone driver contained in an SO8, DIP8 or a TSSOP8 plastic package. The TDA1308AUK is available in an 8 bump wafer level chip-size package (WLCSP8). The device is fabricated in a 1 m Complementary Metal Oxide Semiconductor (CMOS) process and has been primarily developed for portable digital audio applications. The difference between the TDA1308 and the TDA1308A is that the TDA1308A can be used at low supply voltages. 2.

A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description". 14.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 14.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: * Through-hole components * Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: * * * * * * Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus PbSn soldering 14.3 Wave soldering Key characteristics in wave soldering are: * Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave * Solder bath specifications, including temperature and impurities TDA1308_A_4 Product data sheet (c) NXP B.V. 2007. All rights reserved. Rev. 04 -- 25 January 2007 14 of 19 TDA1308; TDA1308A NXP Semiconductors Class-AB stereo headphone driver 14.4 Reflow soldering Key characteristics in reflow soldering are: * Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 16) than a PbSn process, thus reducing the process window * Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board * Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 8 and 9 Table 8. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) < 350 350 < 2.5 235 220 2.5 220 220 Table 9.
