We have recently enacted a new quality directive that requires that we ship certificates of conformance with each solder sphere size / type (alloy) ordered. The certificate is packed in the box that is sent to you. We use these certificates internally to confirm that alloy purity specifications meet industry standards and that size distribution and roundness requirements statistically meet our quality guidelines. Finally we track each order to it’s lot code which we place on your order records (internal to EasySpheres) and provide this lot code on the vials / jars which you receive.

An example of our certification of conformance can be seen below:
