does anyone have experience with reflow of Micro SD cards to PCB@ lead free temps?

Anyone have experience (good or bad) directly reflow soldering microSD card (Pb-free) to PCB. asking for a friend :)

yes, socket on PCB, SMD type

I forgot to update this. Customer insisted on reflowing SIM card directly to PCB, as per their previous CEM. It worked. No deformation of the SIM card - assembly works - records data to SIM card. Note that using hot air reflow type (rework station)d

Good afternoon. Not sure if this is available at an engineer level. Perhaps and SD card with field service access is necessary. We have two lines with NPM-W's and the most we've been able to do is actuate vacuum on the heads during flow checks.

HI there, I am having problem on the solderability for the fine pitch lead on SD card holder on this pcb.Have tried different kind of temperature settings on the reflow but the problem still occurred.Pls refer to the attached pictures.And when i jus

And this process is using a kind of ceramic jigs..... Does this jig absorb much heat that does not dissipate enough heat to the SD card pins ? Thanks

HI guys, Problem solved.....reason is the SD card's location in on the fixed side of the reflow oven,i believe there is not much convection heat blown towards the component.... Pleased to hear if any rgds

I am guessing a lead free process. From the pictures, I don't neccessarily see any issues, perhaps the leads have wicked up a little too much solder, making the joint look a little starved. But I think I see nice toe and side fillets. In the worst c

A couple things to look at.. Are you using Pb-Free solder? What are the leads of the SD Connector tinned with? Do you have a thermal profiler to use to verify your oven profile? (If not, you may be able to ask a Sales Rep to come in and assist y
