| 02/28/2027 | 518442 - Production Transfer. PSBU is transferring all Hetero molding ( molds & presses) from Lincoln 3104 to Nogales 3105. There are approximately 450 molds and 18 presses to transfer. To facilitate this, a series of PCNs will be issued covering group of molds which use the same resin. | Download | |||
| 08/17/2022 | 511610 - Change to product. currently vertical header housings have drain hole and non-drain hole version housing. the drain holes are no longer needed they were used in the past when PCB boards were being washed and are no longer needed. therefore we are eliminating the drain hole option going forward | Download | |||
| 07/18/2022 | 510809 - Change to product. current vertical header housings have a drain hole and non-drain hole version housing the drain holes are no longer needed (they were used in the past when PCB boards were being washed and are no longer needed) therefore we are eliminating the drain hole option going forward | Download | |||
| 02/14/2022 | 511607 - Retraction of PCN 510948. This PCN is a retraction/ recall of PCN 510809 communicated on 1/18/22 for "current vertical header housings have a drain hole and non-drain hole version housing the drain holes are no longer needed (they were used in the past when PCB boards were being washed and are no longer needed) therefore we are eliminating the drain hole option going forward." the reason for retraction is that part numbers that did not contain the drain hole option were included in the impacted parts list used to create pcn 510809 a new pcn will be created and customers will be notified | Download | |||
| 12/24/2018 | 506262 - Capacity Change or Tool Replacement. This letter is to inform you that another set of tooling is being added to meet the current and future demands of this product.
