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

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

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

Mathematically, measure the component offsets from nominal then calculate the average and the SD of the offsets in x and y. You can then use the following equation to calculate the CpK: CpK = (Process Width - Abs(Average offset)) / (3 * SD offset)

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

yes, socket on PCB, SMD type

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

Hey all, I am currently looking into switching from using Alcohol in our screen cleaner to Zestron SD301. I am confident that it will clean our stencils better, but the cost of Zestron is 3 times that of alcohol. Has anybody done any studies o
