How to Prevent Holds
Consignment orders are defined as when a customer sends components and/or boards in a single box or “kit.”
Unfortunately, 1 out of every 2 consignment kits go hold, which can cause delays of up to 5 days. Here’s why and what you can do about it.
The number one problem with consignment kits is that customers do not send enough extra parts to account for normal attrition. While Summit does not experience much loss, a small amount of overages is required to avoid delay.
2. Substitute Parts
We understand substitute parts are often provided when originally designated parts can not be provided. However, many customers fail to communicate when a change has been made. This means the parts in the kit do not match the part list on the Bill of Materials (BOM). To avoid this issue, please clearly communicate and label part substitutions.
3. Moisture-Sensitive Parts
When customers provide parts, they are often loose or in opened bags. This can cause a serious problem if a part is installed that isn’t moisture-free or needed to be pre-baked prior to assembly. Also, there is no way to determine the shelf-life of the part.
4. Inconsistent Labeling
There are many ways parts are labeled. First, customers often have their own, internally-developed part designation system. Then there’s the label given to a part by the manufacture or manufacturers. PCB assembly companies also give parts reference designators once the BOM is checked by design-for-assembly software. Without careful attention to detail it is easy to label different parts with different designators. This is why Summit’s assembly facility always provides kit labels for consignment orders.
5. Split Kits
When customers have multiple jobs being assembled at the same time, they often put the parts and boards for all jobs in a single box without indicating which parts / boards are to be used for which project. Not only can this cause delays while Receiving splits the kits, it also greatly increases the chances for lost or misplaced components.
6. Waiting for Your Response
Assembling jobs correctly the first time is our top priority. When there are questions with consignment kits, we reach out to customers for clarification. How quickly the issues are resolved is up to you. While some customers get back to us in minutes, many can take days, causing significant delays on their projects.
