IEC 62326-1:2002 pdf download.Printed boards -Part 1: Generic specification.
NOTE The customer is reminded of the possibly increased cost of including additional tests or specifying unnecessarily tight sample size selection.
The Cap DS and CDS each have two functions:
— to define the conditions of testing and qualification;
— to describe the product to be delivered.
A survey of the structure of the specification series is given in annex B. Further details of both
Cap DS and CDS, as well as rules for their preparation, are given in clause 7.
4 Particular stipulations
4.1 Primary stage of manufacture
The primary stage of manufacture is defined as the incoming inspection of the materials used for the manufacturing of the printed board materials (i.e. copper-clad laminates, plating chemicals, solder resist, etc.) prior to processing.
This stage, and all subsequent processes, shall be carried out under the authority of the designated management representative (DMR) with defined authorities (formerly known in the IECQ as the chief inspector). Where this first and subsequent stages of processing are carried out by a subcontractor, capability approval may be granted provided that in each case the equivalent disciplines apply.
4.2 Structurally similar printed boards
Printed boards having all of the following common features are considered as structurally similar:
— the same types of base material, for example, 61249-2-4-IEC-EP-GC-Cu;
— the same type of printed board, for example, rigid single and double-sided printed boards without interlayer connections or rigid single and double-sided printed boards with interlayer connections or rigid multilayer printed boards with interlayer connections;
— the same type of surface finish, for example tin-lead and/or gold and/or copper;
— approximately similar product complexity.
4.3 Certified records of released lots (CRRL)
The content of certified records shall be as prescribed in 6.1 and 6.2 of this GS and in the relevant SS, stating the number of specimens tested.
4.4 Delayed delivery
When printed boards are held by the manufacturer for a period of more than six months after the quality conformance inspection, the following tests shall be carried out prior to delivery:
— solderability test 3X07 as specified for quality conformance inspection, in the relevant CDS; (to include the specified baking requirement of Test 3X07).
— visual examination of the appearance, as specified for quality conformance inspection in the relevant CDS.
4.5 Release for delivery before the completion of all tests
The manufacturer is permitted, with the agreement of the customer, to release printed boards before the completion of periodic (monthly or quarterly) tests or lot inspection tests which take more time (for example, solder test after accelerated ageing).
4.6 Re-submission of rejected lots
Where a sample fails to meet the requirements of a periodic test, action shall be taken in accordance with 4.2.10 of IEC QC 001002-3.
4.7 Marking of printed boards and package
4.7.1 Printed boards
Each printed board shall be clearly and permanently marked with the reference specified by the customer.
The marking may, for example, be printed with permanent ink, be formed with a metal pattern, be integrated as part of the permanent polymer coatings, etc.
Marking with additional information, such as manufacturer’s name or identification code, number of the SS, date code, etc. may be applied if explicitly agreed between manufacturer and customer.
The location of any marking shall be agreed between manufacturer and customer.
4.7.2 Package
The package shall be marked with the information given in 4.7.1 and any special marking required by the CDS (for example, customer’s identification number).
4.8 Ordering information
Printed boards shall be ordered in accordance with the CDS. The CDS shall contain or reference all information necessary to define the printed board clearly and completely.
5 Capability approval and maintenance of capability approval
5.1 General
This clause states the requirements and procedures for obtaining capability approval and for the maintenance of capability approval.
In the case of printed boards, a manufacturer’s capability is divided into two parts:
— product capability. This capability is defined in the IEC Cap DS. The materials used to make the product covered by the SS are also specified in the Cap DS. Examples of product characteristics are board size, hole diameter, number of layers, etc.;
— process capability. This capability, also defined in the Cap DS, is granted for defined processes. Examples of processes are “in-house” photoplotting, gold plating, solder coating (levelled), etc.
