www.ipc.orgDuring solder reflow, the combination of rapid moisture expansion, materials mismatch, and material interface degradation can result in cracking and/or delamination of critical interfaces within the device. Typical solder reflow processes of concern for all devices are convection, convection/IR, infrared (IR), vapor phase (VPR), hot air
IPC/JEDEC J-STD-020C Moisture/Reflow Sensitivity ...
ferroxcube.home.pl3.2.2 Infrared Infrared (IR)/convection solder reflow equipment capable of maintaining the reflow profiles required by this standard. It is required that this equipment use IR to heat only the air and not directly impinge upon the SMD Packages/devices under test.
Best Practices Reflow Profiling for Lead-Free SMT Assembly ...
kicthermal.comSolder balling occurs if the solder paste spatters (small “explosions”) during reflow, or if the paste slumps and the flux spreads, carrying away solder particles which cannot reflow back into the solder mass. A maximum ramp rate from ambient to peak of 1-1.5°C/second is recommended. If the solder paste is heated too quickly,
sac305 Lead-free solder alloy
aimsolder.cominclude Wave, Selective, Hand and SMT Reflow Soldering. AIM Electropure™ SAC305 Shelf Lifebar solder offers reduced dross production and superior wetting and fluidity as compared to other solder brands. AIM’s SAC305 bar solder is alloyed using our proprietary Electropure™ method resulting in a low drossing, high wetting solder.
MSL Ratings and Reflow Profiles (Rev. A)
www.ti.comFor the customer production reflow soldering process, the peak reflow temperature (Tp) has to be lower than the classification reflow temperature (Tp) shown in Table 2 and Figure 3. The reflow profile and peak temperature should be in line with the solder paste manufacturerer recommendation and all used
Difference Between Various Sn/Ag/Cu Solder Compositions
www.almit.comthe traditionally used Sn-Pb solder is being restricted (RoHS etc.) From reliability standpoints, Sn/Ag/Cu alloys has been chosen as the replacement for Sn-Pb solder. However, there is no industry standard on which alloy to chose among the various Sn/Ag/Cu alloys available in the market. - Sn + 3.9% Ag + 0.6% Cu (iNEMI recommended)
