Soldering of WLCSP packages 10.1 Introduction to soldering WLCSP packages This text provides a very brief insight into a complex technology. A more in-depth account of soldering WLCSP (Wafer Level Chip-Size Packages) can be found in application note AN10439 “Wafer Level Chip Scale Package” and in application note AN10365 “Surface mount reflow soldering description”. Wave soldering is not suitable for this package. All NXP WLCSP packages are lead-free. 10.2 Board mounting Board mounting of a WLCSP requires several steps: 1. Solder paste printing on the PCB 2. Component placement with a pick and place machine 3. The reflow soldering itself 10.3 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 9) than a PbSn process, thus reducing the process window • Solder paste printing issues, such as 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) while being 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 7. Table 7. Lead-free process (from J-STD-020C) Package thickness (mm) Package reflow temperature (C) Volume (mm3) IP4340CX15 Product data sheet < 350 350 to 2000 > 2000 < 1.6 260 260 260 1.6 to 2.5 260 250 245 > 2.5 250 245 245 All information provided in this document is subject to legal disclaimers.

All rights reserved. 8 of 14 IP4340CX15 NXP Semiconductors 6-channel filter for ESD protection of microSD memory card interfaces 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 9. maximum peak temperature = MSL limit, damage level temperature minimum peak temperature = minimum soldering temperature peak temperature time 001aac844 MSL: Moisture Sensitivity Level Fig 9. Temperature profiles for large and small components For further information on temperature profiles, refer to application note AN10365 “Surface mount reflow soldering description”. 10.3.1 Stand off The stand off between the substrate and the chip is determined by: • The amount of printed solder on the substrate • The size of the solder land on the substrate • The bump height on the chip The higher the stand off, the better the stresses are released due to TEC (Thermal Expansion Coefficient) differences between substrate and chip. 10.3.2 Quality of solder joint A flip-chip joint is considered to be a good joint when the entire solder land has been wetted by the solder from the bump. The surface of the joint should be smooth and the shape symmetrical. The soldered joints on a chip should be uniform. Voids in the bumps after reflow can occur during the reflow process in bumps with high ratio of bump diameter to bump height, i.e. low bumps with large diameter. No failures have been found to be related to these voids. Solder joint inspection after reflow can be done with X-ray to monitor defects such as bridging, open circuits and voids.

All rights reserved. 9 of 14 IP4340CX15 NXP Semiconductors 6-channel filter for ESD protection of microSD memory card interfaces 10.3.3 Rework In general, rework is not recommended. By rework we mean the process of removing the chip from the substrate and replacing it with a new chip. If a chip is removed from the substrate, most solder balls of the chip will be damaged. In that case it is recommended not to re-use the chip again. Device removal can be done when the substrate is heated until it is certain that all solder joints are molten. The chip can then be carefully removed from the substrate without damaging the tracks and solder lands on the substrate. Removing the device must be done using plastic tweezers, because metal tweezers can damage the silicon. The surface of the substrate should be carefully cleaned and all solder and flux residues and/or underfill removed. When a new chip is placed on the substrate, use the flux process instead of solder on the solder lands. Apply flux on the bumps at the chip side as well as on the solder pads on the substrate. Place and align the new chip while viewing with a microscope. To reflow the solder, use the solder profile shown in application note AN10365 “Surface mount reflow soldering description”. 10.3.4 Cleaning Cleaning can be done after reflow soldering.
