This part of IEC 61249 gives requirements for flexible polyester (PETP) films coated on one side or both with polyester, acrylic or epoxide type adhesive for use in the fabrication of flexible printed wiring. Films coated on only one side are used as a coverlay or covercoat in the fabrication of flexible printed wiring. This coverlay or covercoat is also used to provide local support to areas subjected to mechanical or environmental stress. Films coated on both sides are used as bonding films in the fabrication of printed boards.

This part of IEC 61188 provides information on land pattern geometries used for the surface attachment of electronic components with gull-wing leads on four sides. The intent of the information presented herein is to provide the appropriate size, shape and tolerances of surface mount land patterns to ensure sufficient area for the appropriate solder fillet, and also allow for inspection, testing and reworking of those solder joints. Each clause contains a specific set of criteria such that the information presented is consistent, providing information on the component, the component dimensions, the solder joint design and the land pattern dimensions. The land pattern dimensions are based on a mathematical model that establishes a platform for a solder joint attachment to the printed board. The existing models create a platform that is capable of establishing a reliable solder alloy used to make that joint (lead-free, tin lead, etc.). Process requirements for solder reflow are different based on the solder alloy and should be analyzed in order that the process is above that temperature a sufficient time to form a reliable metallurgical bond.

This specification within the IEC 61249 series details requirements for the qualification of temporary solder resist coatings. These have been referred to as a mask in this specification since they have the facility of being readily removed. Peelable solder masks are applied (usually by screen printing) to areas of a completed printed board or panel prior to shipment, in order to protect areas of the board or panel during subsequent processes by the board assembler. Typically, peelable solder masks are used to protect keypad contacts during fluxing and subsequent mass soldering. Removal of the mask will then leave a residue-free untinned contact area. Requirements stated in this specification will also have some limited validity for assessing the suitability of printed boards which are supplied with peelable solder masks. Requirements for the release of printed boards using peelable solder masks should be included in the Customer Detail Specification (CDS). Requirements for the qualification of permanent polymeric solder resistive coatings are given in IEC 61249-8-51) , which has been used as a template in constructing this specification, in as far as it may apply.

This part of IEC 62326 defines capability approval (CA) procedures for printed boards. When IECQ recognition is required, the capability approval procedures of IEC 001002 should be used. In addition, a technology approval (TA) schedule may also be provided as an alternative for manufacturers employing a system of process control for establishing product conformity. Both CA and TA procedures apply to printed boards irrespective of their methods of manufacture, when they are ready for the mounting of components. The information and requirements may also be used for second-party approvals or for self-declaration by a manufacturer of products covered by these specifications.

This part of IEC 61188 provides information on land pattern geometries used for the surface attachment of electronic components with area array terminations in the form of solder balls, solder columns or protective coated lands. The intent of the information presented herein is to provide the appropriate size, shape and tolerances of surface mount land patterns to ensure sufficient area for the appropriate solder joint, and also allow for inspection, testing and reworking of those solder joints. Each clause contains a specific set of criteria such that the information presented is consistent, providing information on the component, the component dimensions, the solder joint design and the land pattern dimensions. The land pattern dimensions are based on a mathematical model that establishes a platform for a solder joint attachment to the printed board. The existing models create a platform that is capable of establishing a reliable solder joint no matter which solder alloy is used to make that joint (lead-free, tin lead, etc.). Process requirements for solder reflow are different depending on the solder alloy and should be analyzed so that the process is taking place above the liquidus temperature of the alloy, and remains above that temperature a sufficient time to form a reliable metallurgical bond. Area array land patterns do not use "land protrusion" concepts and attempt to match the characteristics of the physical and dimensional termination properties. There are several configurations available, as shown in Figure 1. However, the tables provided show only the optimum dimension across the outer construction of the land.
