IPC APEX EXPO 2014 | Year: 2014

On January 1, 2015, nine months from APEX 2014, the production and use restrictions on HCFC-225 will be in effect throughout the United States. This phase out is encompassing in scope. This phase out will have significant technical, performance, and economic implications for the electronics industry. The regulatory situation remains fluid. A number of alternative solvents have been or are in the process of being developed. We discuss the options for assemblers and component manufacturers.

Several factors that need to be considered by manufacturers when selecting cleaning agents are presented. Water is an excellent for removing inorganic compounds such as salts). Most organic solvents tend to be better solvents for oils and greases. The Kauri Butanol (KB) number and the Hansen solubility parameters are two popular approaches to solvency. The KB number provides a single dimension indicating relative solvency in terms of shades of grey. Understanding Hansen Parameters can also be helpful if the soils change or if there is product damage associated with using a given cleaning process with new materials of construction. The physical properties of the cleaning also influence the optimal choice. The density, surface tension, and viscosity all influence the wettability, the extent to which the solvent can penetrate densely-spaced components or ornate parts. The boiling point of the cleaning agent must also be considered. Solvency parameters and wettability are generally calculated at ambient temperature.

ASTM International Standards for critical cleaning and contamination control has wide-ranging, encompassing implications. There is no ASTM standard regarding validation of what is termed clean lines for medical devices. The clean lines encompass the medical device product itself as well as the cleaning process and cleaning equipment. The standard practice is geared to manufacturers performing final product assembly. However, it also encompasses the cleaning, contamination control, and surface quality of incoming parts or components, parts produced by outside suppliers. The standards being developed by ASTM generally fall into one of two categories. There are basic how to documents with specific recipes for setting up and performing a process or test. There are also guidance documents that suggest how to write the recipes; how to develop, maintain and document the process and test protocols that can be used consistently.

The International Thermal Spray Association (ITSA) 2010, which was held in San Francisco, emphasized on the professional development, including certification, advanced technical developments, and the safety/regulatory developments. Dan Hayden, President of Hayden Corporation in West Springfield, Massachusetts, explained that thermal spray operations are being regulated in an analogous manner to plating operations. Regulators do not seem to differentiate between thermal spray activities and plating. Hayden mentioned that in the US, regulators are taking a precautionary approach, so they may utilize their limited resources and personnel by looking at existing regulations and then adding more layers. Many involved in thermal spray would like to be involved in rule development that ensures protective, defensible, scientifically-based, and enforceable regulations. J. Dowell, President and CEO of Plasma Technology Inc. explained that thermal spray is becoming increasingly important in automotive applications, for piston rings and valve-train assemblies.

Biobased materials are favored over synthetic hydrocarbon, petroleum-based materials because they are based on renewable resources and therefore can be more readily reproduced. Introduction of biobased products has reduced dependence on importation of petroleum product from areas where there may be political and economic issues. An understanding of the extent to which hydrolysis could be controlled would go a long way to better understanding where biobased esters could best be used. Experts suggest that selecting highly-processed biobased oils with a high oleic-content. This processing and purification significantly increases the cost. Biobased cleaning agent and other biobased process fluids need to be developed as chemicals from renewable rather than as inherently superior natural products.

Various regulatory provisions have been made and are being revised targeted towards employee safety in a chemical industrial working environment. In the US, the Occupational Health and Safety Administration (OSHA) sets legally-enforceable worker exposure limits for airborne chemicals. In California, the Division of Occupational Safety and Health, also known as Cal/OSHA, is setting worker exposure limits for many chemicals, and the trend tends to be toward lower and lower limits. The Health Expert Advisory Committee (HEAC) deliberates and then recommends either a single worker exposure limit or a range of exposure limits. Representatives from OEHHA have presented reports and analysis pertaining to extrapolation to fit the worker population and complex toxicological studies in this direction. Industry experts at the HEAC and FAC assert that the chemical need to be provided with a sufficiently high permissible exposure limit.

The Significant New Alternatives Policy (SNAP) Program was developed during the late 1980s to early 1990s. The initial SNAP Advance Notice of Proposed Rulemaking was January 16, 1992. Manufacturers developing new solvents might need to submit information to the EPA SNAP program. Any substance that is not on the Toxic Substances Control Act (TSCA) Chemical Substance Inventory list is classified as a new chemical. Since the initial SNAP listings, additional chemicals have become restricted as an ODS. Within the EPA, SNAP is chartered to both evaluate and regulate substitutes for ozone depleting chemicals that are being phased out of production. The lists of substitutes published by SNAP have profound social, economic, and environmental consequences. Determinations by SNAP may determine the economic fate of chemical manufacturers and they may strongly influence the course product manufacturing.

Achieving high reliability cleaning may involve expanding the types of cleaning agents and cleaning systems under consideration. Electronics assemblers have generally been concerned with ionic contamination, with conductivity issues. Conductive residue results in immediate performance and reliability issues. Fourier transform infrared spectroscopy (FTIR) can be used as a monitoring method to provide a profile of organic contamination. Some groups use high-performance liquid chromatography (HPLC) to separate organic compounds. To obtain clean components, manufacturers have to select reliable suppliers and partner with them. They must focus on flux as a contaminant; their suppliers may use an assortment of process fluids, including lubricants. Metalworking fluids are complex blends of organic and inorganic compounds. In cleaning high-reliability assemblies, it is often effective to move beyond the jargon of what batch and in-line mean. Partnering is one secret to electronics assembly of high-reliability products.

A well-defined, consistent cleaning process can greatly assist one's customer. An effective cleaning process means one that removes the soils of interest, does not damage the product, leaves the surface in the appropriate condition, and minimizes leachable residue. People used to equate critical cleaning or precision cleaning with processes conducted by whitegarbed individuals working in a cleanroom. Cleaning process consistency is a must. Consistency involves avoiding unanticipated changes. This means selecting an optimal cleaning agent, quality cleaning equipment, and achieving a rugged process. The bottom line is that because metalworking fluids are being formulated with less volatile, higher boiling chemicals, there is the potential for more residue to stick to the surface. One may be working with a manufacturer that is developing a new medical device. The way one designs one's product and the way one supplies one's product can impact the critical cleaning during final assembly and can impact product quality. If one's customer has not spoken with one, one may find it useful to begin the dialog.

Consider defluxing at the design stage. This involves determining how product design may impact the assembly process. It also involves selecting the most effective, rugged defluxing option relative to the assembly design. The reward is reliable, competitive, and profitable electronics assembly. Selecting the right defluxing process must take into consideration not only performance requirements and costs but also miniaturization, component configuration, as well as local, national and international regulatory constraints. Changes in product design and the increase in highly-populated assemblies may impel modification of the defluxing process. Changes in the defluxing chemistry and in the defluxing process can benefit product quality and performance.
