Soldering - University of Technology Sydney

Tin/lead solder is still available and is used by “hobbyists” and other non-commercial users as it is still easier to use than lead free types. When using tin/lead (or leaded) solder there are additional safety precautions that must be observed. Different gauges of solder wire Solder composition is labelled (Lead free on left) Figure 3 ...

solder or using conductive adhesive. By far, the most common packaging interconnect is solder. Current solder options are eutectic Sn/Pb or lead-free (98.2% Sn, 1.8% Ag) compositions. The solder bumped die is attached to a substrate by a solder reflow process, very similar to the process used to attach BGA balls to the package exterior.

• Liquidous temperature (TL) for lead-free soldering - this is approximately 217°C. This varies according to the used solder alloy. • The Peak temperature (Tp) for the reflow profile, measured at top of the package. – For the user (board assembly process), Tp must not exceed Tc as shown in Table 2.

SMT Board Assembly Process Guide - Intel

Pb-free Reflow Soldering Pb-free reflow requires relatively high temperatures, due to the high melting range of typical Pb-free solders. Typical Pb-free solder such as SAC305 (Sn/3Ag/0.5Cu) have s an initial melting point of 217°C and a final melting point of 220°C. Pb-free reflow soldering requires a narrow temperature range, in order

Soldering Guidelines for Mounting Bottom-terminated …

The solder paste is the vehicle that provides the flux and solder alloy necessary for a reliable and consistent assembly process. A low residue, no-clean solder paste (eutectic Sn63/Pb37 or lead-free SAC305/405 alloy SnAgCu) is commonly used. A water-soluble paste can be used if the residue can be adequately cleaned from underneath the package.

Recommended Soldering Techniques

with the intended mounting plane. In an infrared reflow solder process, the PCB pads are coated with a solder paste (Figure 3). When the assembly is heated in an oven, the solder paste warms and reflows. As the solder paste liquefies, it forms an apex at the center of the PCB pad. This apex must contact the terminal of the device

Solder paste grain size can be useful to manipulate by pitch. For larger pitch parts, 0.80 mm and larger, Type 3 solder powder (25 to 45 micron grain size) is widely used. At the pitches, 0.65 mm and smaller, Type 4 solder (20 to 38 microns grain size) may provide a better solder joint.
