IP4286CZ6
Integrated 4-channel ESD protection
Rev. 01 -- 20 April 2009 Objective data sheet
1. Product profile
1.1 General description
The IP4286CZ6 is designed to protect the capacitive loads of Input/Output (I/O) ports (such as USB 2.0, Ethernet, DVI etc.) from being damaged by ElectroStatic Discharge (ESD). To provide ESD protection to downstream signal and supply components, the IP4286CZ6 incorporates four pairs of ultra-low capacitance rail-to-rail diodes plus two Zener diodes. This provides protection against contact discharge voltages as high as 8 kV in accordance with IEC 61000-4-2, level 4. The ESD protection is independent of the supply voltage due to the rail-to-rail diodes being connected to a Zener diode. The IP4286CZ6 is fabricated using monolithic silicon technology and integrates 4 ultra-low capacitance rail-to-rail ESD protection diodes plus two Zener diodes.
1.2 Features
I Pb-free and RoHS compliant I ESD IEC 61000-4-2 level 4, 8 kV contact discharge compliant protection I Four input ESD rail-to-rail protection diodes with ultra-low input capacitance of 0.6 pF maximum I Low-voltage clamping due to integrated Zener diodes
1.3 Applications
General-purpose downstream ESD protection high frequency analog signals and high-speed serial data transmission for ports inside: I PC/Notebook USB 2.0/IEEE 1394 ports I Cellular and PCS mobile handsets I DVI interfaces I HDMI interfaces I Cordless telephones I Wireless data (WAN/LAN) systems I PDAs

8. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account of soldering ICs can be found in Application Note AN10365 "Surface mount reflow soldering description".
8.1 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.
8.2 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 SnPb soldering
8.3 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

8.4 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 5) than a SnPb 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 5 and 6
Table 5. SnPb eutectic process (from J-STD-020C) Package reflow temperature (C) Volume (mm3) < 350 < 2.5 2.5 Table 6. 235 220 Lead-free process (from J-STD-020C) Package reflow temperature (C) Volume (mm3) < 350 < 1.6 1.6 to 2.5 > 2.5 260 260 250 350 to 2000 260 250 245 > 2000 260 245 245 350 220 220

Moisture sensitivity precautions, as indicated on the packing, must be respected at all times. Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 5.
