![]() Unless otherwise specified in the drawing, printed circuit boards shall be packed in static shielding packaging.To help ensure board performance for PCAs/PCBs, IMSAR, LLC requires that suppliers follow the guidelines set forth below for the storage and packaging environments of PCBs. For PCBs using Rogers RO4450B Prepreg or RO4450F Prepreg, include a report documenting the pressure applied to parts during the lamination cycle.If test reports were supplied with a previous delivery, it shall be noted in the C of C. Also included are a serialization sheet detailing the serial numbers for all parts in the delivery, and any other test results required by the drawing or purchase order. ![]() For example, a conformal coat treatment should include at least coating material type, measured thickness, and measured tolerance. Include a Certificate of Conformance (C of C) that includes information about the treatment type with each order.Marking shall be indelible and applied to both sides. Each X-Out board shall be marked in a manner so as to make the X-Out obvious.Each panel will contain no more than “N” number of X-Outs of PCBs per panel.IMSAR, LLC will allow for the receipt of X-Outs on PCB panels with the following conditions: It is paramount that untreated/uncoated silver immersion finished PCAs/PCBs not be handled with bare skin contact. Suppliers shall reference IPC-A-610, Chapter 3 Handling Electronic Assemblies to meet this requirement. Quality system specifications ISO 9001 and SAE AS9100 require these procedures. Suppliers should have documented procedures that outline these preventative practices. ![]() Suppliers shall ensure PCAs/PCBs are protected from environmental, handling and storage damage. To prevent Electro-Static Discharge (ESD) and Electrical Over Stress (EOS) damage to sensitive components all handling, unpacking, assembly and testing shall be performed at a static-controlled workstation. MaterialsĪll printed circuit assembly treatments will adhere to the materials specified in the master drawing. ![]() It is the responsibility of the subcontractor or supplier to meet all requirements expressed in the purchase order, fabrication drawings, applicable IPC standards, fabrication instructions (such as “readme” files), and this document unless specific written permission for deviation is issued by IMSAR, LLC. This document contains allowable PCA/PCB handling, storage, and shipping standards applicable to IMSAR’s suppliers. This document contains the specifications set forth for all Printed Circuit Assemblies (PCA) and Printed Circuit Boards (PCB) that are handled by IMSAR, LLC or its subcontractors or suppliers. ![]()
