Attrition Standards and Conditions

We cannot begin assembly on your order until we receive sufficient additional components to account for attrition. Due to the small size of many parts and the high speed of automated placement equipment, a small number of components may be lost or damaged during setup and processing, as is common in electronics manufacturing.

If we do not receive the required extra parts, your order may be placed on hold while we contact you to resolve the shortage. This can result in delays to your assembly schedule.

If certain components are high in cost and meeting our standard attrition requirements would create a financial hardship, please notify your Customer Service Representative. Provide the part number and reference designator(s) so we can review and account for the shortage(s) appropriately.

To avoid unnecessary delays and ensure a successful build, please follow our Revised Attrition Standards and Conditions outlined below. If you have any questions, please contact our Customer Service Team via chat or email at sales@screamingcircuits.com.
