2.0V at 0.1mA for InGaN product and >1.4V at 0.1mA for AlInGaP product." It's common for ESD protection programs to conform to ANSI/ESD S20.20 - Protection of Electrical and Electronic Parts, Assemblies and Equipment (Excluding Electrically Initiate

We have to mount our SMD devices 0.1 to 0.4 mm off the pcb PCb substrate to compensate for thermal stressing in a Space enviroment. Has any one any ideas or contacts for dissolvable pads. this only applies to leadless components

Thanks for your response. Yes Tombstone is happening in same direction only. We can't rotate every board since the issue is random and the defect rate is around 0.1% Already using high soak profile. Stencil modification in progress.

My recollection is that RoHS limits for lead is 0.1% of the weight of any homogeneous material in the assembly.

Solder balls that have more than 0,1% PB are not RoHS compliant. It might be RoHS compatible meaning it can handle the higher temperatures used in a leadfree process.

DeanM, if I understood correct, you use fiducial with dimension 0.1 mm and increased it to 0.15 mm. Why use use small fiducials? You don't have free space on your PCBs?

I have been wave soldering LCD's for about five years now and have done many thousands. As someone else mentioned they go dark when heated but then clear as the temp comes back down. The amount of failures attributable to the wave process has been l

Sorry if info is useless, but placement machines must have own system programs for completly ajustment of placement in a gap about 0.01 mm . Also headblock camera has enought increment to found correct place and fiducial setups utility. Maybe your lo

We had this problem with 0805 0.1 mF also. This problem was only with this capacitor. We have replaced all these capacitor after the ninth occurrence. My opinion - it is a defect of the manufacturer. Please inform the manufacturer of your capacitor.
