Yes all above is correct, as solder deposits get smaller and mesh T4+ , actual metal to air contact surface area increases , say in contrast to T3, add to this less flux , and flux running away from the joint, re-oxidation and what flux is left, can

Dear Abhishek, I too got the opportunity to investigate this defect Lift lead for SOT. Lead lift in IC, and SOT can occur due to various reasons. Here are some possible reasons for lead lift and ways to avoid them: During the assembly process, mecha

The real causes of microcracking are not normally due to pick and place - particularly if you are using a piece of equipment with vacuum pick up and release. The real cause of microcracking is due to thermal stresses on the die and the choice of the

https://www.jrpanel.com/R The heat generated by electronic equipment causes the internal temperature to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up and the components will overheat and fail, resulting

Notes from an AIM No-Lead Presentation ... Wave Soldering * May require a higher pot temperature than tin/lead: 255-265*C * May require a change in liquid fluxes to compensate for the poor wetting of some alloys and high thermal stresses of the wave
