In any manufacturing business, product quality is vital to producing products that meet the reliability standards that customers require. Line efficiency is equally important such that the quality products demanded are produced in a cost effective manner for the seller and offered to the buyer such that the price value is recognized. Process improvements are constantly sought, however, when a new customer specification cannot be achieved, line deficiencies must be identified and corrected.

The revised standards must then be established and implemented in an organized and time sensitive manner. Initial tests utilizing their current processes were not successful due to the presence of flux residues. This was attributed to deficiencies in the cleaning process. Thus began the analysis of their SMT procedures with particular emphasis on the cleaning process that was utilizing an aqueous cleaning agent and a spray-in-air inline cleaner.

Numerous process variables were reviewed and adjusted in a sequential manner throughout the DOE process. This included cleaning agent characteristics, such as concentration, and the inline cleaner set-up including spray bar number, nozzle type and configuration, spray bar pressure, wash and rinse temperature, and belt speed. Cleaning agent bath quality was also monitored. Through all steps of the DOE, improvement progress was validated initially through visual inspection and finally through the successful passing of the required SIR testing.

The IPC-B coupon has traditionally been the electronics industry s primary test vehicle TV for evaluating flux chemistries and surface insulation resistance SIR as it provides a quick and easy way to evaluate individual fluxes as well as mixing effects. Although useful, this design is not an ideal test vehicle for assembly manufacturers to evaluate fluxes using actual production equipment and assembly processes, as it consists of only single sided surface traces, without surface mounted or wave soldered components. This shortcoming, over the years, has driven the development of various company unique SIR test vehicles. It is much more capable of assessing SIR concerns with flux chemistry that result from the presence of components. As the industry continues to migrate to lead free soldering for higher complexity hardware assemblies, and new flux chemistries are introduced, it is projected that the adoption and usage of the new IPC-B coupon will continue to rise.

There are several ways to measure residues and their effects on electrical performances. The two most common in the industry are ionic cleanliness testing for determination of ionic residues , and surface insulation resistance SIR testing for the evaluation of electrochemical failures in humid environments.

There are several different ways to measure residues and their effects on electrical performances, the two most common in the industry are ionic cleanliness testing, for determination of ionic residues, and surface insulation resistance SIR testing, for the evaluation of electrochemical failures in humid environments. Of the various methods for determination of ionic residues, the method of choice is ion chromatography, which determines both the type of ionic residue and the amount of the residue. Consequently, a test vehicle was needed which could be used for both ion chromatography and surface insulation resistance testing, but which was more representative of mainstream manufacturing materials and process.

Such a determination may be a monitoring or changing of an existing in-house manufacturing process, the development of a new manufacturing process, or determining if assemblies produced by a subcontractor are acceptable. The concept of materials compatibility can be very broad, depending on what factors are chosen for examination, but is critical to understanding the reliability of manufactured hardware. This paper focuses on the use of the IPC-B standard printed wiring assembly as a test vehicle to meet these needs, with illustrative data from a high reliability avionics manufacturing process, including lead-free evaluations.

A longtime user compares and contrasts the ECAD formats. Designers and engineers are getting paid more. But are they working harder for a living? ENIG specs call for examination corrosion for a continuous intermetallic formed between the nickel layer and bulk solder. Can solder wetting balance testing predict the acceptability of ENIG deposits with level 2 or 3 corrosion? Many electronic engineers leave Maxwell to the textbooks. But in logic, the rise times for signals are often less than a nanosecond — bandwidth that invites unwanted radiation, interference and crosstalk. Samples subjected to typical end-use qualification testing revealed the importance of the application technique on the performance of certain coatings.

The electronics industry has long struggled to find a single, ideal test vehicle to evaluate concerns associated with surface insulation resistance of printed circuit board assemblies.

Surface Insulation Resistance SIR , as defined by IPC, is the electrical resistance of an insulating material between a pair of contacts, conductors, or grounding devices that is determined under specified environmental and electrical conditions. When developing an SIR testing strategy, the product or process selected for testing will help determine the most appropriate SIR test method as well as determine the most applicable test vehicle. It is characterized by a sudden loss of insulation resistance that happens internally in the PCB. Plating chemistry, material consistency, damage from multiple soldering steps, and excessive voltages beyond designed voltages accelerate the onset of CAF. The mechanism of CAF is an electro-chemical transport of ions across an electrical potential between anode and cathode. It is usually performed on industry standard test board coupons containing patterns, typically interlocking comb test patterns designed for process testing purposes. The patterns are exposed to a high humidity environment which mobilizes any surface contaminates and reduces the insulation resistance of the test pattern. Implementing a new assembly process step or chemistry can be detrimental to end-product performance. The new IPC is designed to help validate and record the effects of new processes on the surface insulation resistance SIR.
