This part of IEC 61188 provides information on land pattern geometries used for the surface attachment of electronic components with gull-wing leads on two 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.

This part of IEC 61249 gives requirements for properties of prepreg that is mainly intended to be used as bonding sheets in connection with laminates according IEC 61249-2-7 when manufacturing multilayer boards according to IEC 62326-4. This material may be also used to bond other types of laminates. Prepreg according to this standard is of defined flammability (vertical burning test). The flammability rating on fully cured prepreg is achieved through the use of non-halogenated fire retardants contained as an integral part of the polymeric structure. After lamination according to the supplier’s instructions, the glass transition temperature is defined to be 120 °C minimum.

This specification gives the requirements for copper-clad Invar material for use in the fabrication of metal-clad laminated sheets, used for printed boards. The use of copper-clad Invar material in printed boards modifies some properties of the boards, for example thermal capacity and coefficient of thermal expansion. This specification covers copper-clad Invar material of nominal thickness from 0,1 mm to 2,4 mm. It applies mainly to copper-clad Invar material supplied in rolls, but by agreement between purchaser and supplier it may be applied to copper-clad Invar material produced in sheets.

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.

IEC 62496-1 applies to optical circuit boards possessing all of the following general features: – transmit patterns with straight, cross, bending optical paths and input and output optical ports in plane; – optical paths consisting of optical fibres and/or optical waveguides; – controlled lengths of the optical paths, if required; – may be combined with a printed electric circuit board, the functionality of which is outside the scope of this standard; – functions to interconnect between optical components and the ability to mount components. The purpose of this standard is to specify optical circuit board requirements as they relate to − classification, − IEC standard system, − documentation, − materials, − workmanship, − performance, − identification − packaging.

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.
