33.1.3 History Solder mask began with the use of two-part epoxy, thermally curable inks that were an offshoot of inks that were used in the printing industry. These inks were applied by screen printing with the use of a patterned screen, since these materials were not photoimageable. One-part inks that were ultraviolet (UV) curable were available soon after, but these also had to be applied by a patterned screen because they could not be imaged and developed.

Photoimageable solder masks were developed in the mid-1970s and were offshoots of photoresist materials used for patterning the circuitry. Photoimageable solder masks were developed in both liquid (LPI) and dry film (DFSM) and both were used widely. Today, more than 98 percent of the solder mask used is applied in liquid form, and most is photoimageable.

The use of solder mask continues to evolve with the technology. This section discusses some of the issues involved.

Circuit Density Since the development of circuit boards, the dimensions of the holes and features have been decreasing. Smaller component attachment dimensions require corresponding decreases in solder mask features that challenge the solder mask materials and processes. 33.2.1.1 Feature Size. Smaller solder mask features have eliminated non-photoimageable solder masks from all but the lowest technology designs, and continue to require ongoing improvements in resolution and image reproduction. A very high percentage of solder mask being used is photoimageable. 33.2.1.2 Hole Size. Holes in boards that have been coated with LPI solder mask will have some solder mask material in the holes after application. Typically this material must be removed in the development process. There are very significant differences in how easily different solder mask materials develop from holes. There is also a difference in the amount of solder mask material that is in the holes between application methods, with spray and curtain coating leaving less material than screen printing.

Component Attachment in a Lead-Free Environment As many PCB fabricators and assemblers transition to lead-free processing, they are faced with solder alloys that have an operating temperature up to 30 C (54 F) hotter than the traditional eutectic tin-lead solders. These increased soldering temperatures raise concerns about the ability of the solder mask (as well as all other materials) to resist embrittlement, discoloration, loss of adhesion, and cracking with repeated exposures to the higher temperatures. Some existing products may not be acceptable for lead-free processing.

High-Density Interconnection (HDI) HDI technology creates small blind microvias that are plated to provide interconnects to buried layers of circuitry.These small holes can either be coated with solder mask or filled and plated over so that the real estate of the hole can be utilized for a circuit or a component mounting pad (via-in-pad). If the hole is simply coated with solder mask and the solder mask is not developed from the hole, the air trapped in these small holes may expand and create a bubble or blister, or may erupt, exposing the copper in the hole to potentially corrosive chemistries. These holes should be developed cleanly so that they receive the final finish, should be protected before solder mask application with an inert final finish or be completely plugged.

The examples of these instructions are: LDS RD, K; K is a 16-bit address. STS K, Rs; Figure 4.4 illustrates how direct data instructions operate.

Plating over microvias requires that they are totally filled, planarized, roughened, and catalyzed before the plating process. If a conductive plugging material is used, the catalysis step typically can be eliminated. Material selection for this application is particularly important because not many materials can withstand the roughening and plating and still maintain good adhesion of the copper to the plugging material after exposure to soldering temperatures. If the via is in a component mounting pad (via-in-pad), the plugging material must not shrink and cause a significant depression (dimple) in the pad. This is especially true for wire bonding applications that require a very flat planar surface.

Environmental The Restriction of Hazardous Substances (RoHS) Directive 2002/95/EC places restrictions upon specific materials that may be included in PCB fabrication materials, including solder masks. These requirements may require some products to be reformulated. Some products and/or markets may require low-halogen materials to comply with company or industry specifications. Again, these requirements have required some solder masks to be reformulated or new products to be developed. Many localities have strict air emissions regulations that limit the materials and the amount that may be exhausted to the atmosphere. Individual processes or pieces of equipment may require a permit to exhaust any volatile materials. Hazardous air pollutants (HAPs) and volatile organic components (VOCs) are of particular concern. Limits on these parameters can limit mask selection and application processes. For example, curtain coating and spray mask application are not viable in some areas due to the higher percentage of solvent needed for proper application. Screening utilizes solder mask at a much higher percent solids (less dilution), so air emissions may be only half that of other methods.
