Microtronic Provides Cutting-Edge Technologies And Services
The model LBT-210 solderability tester automatically solders and tests today's most challenging circuit constructions.

Microtronic GmbH is a leading specialist of microelectronics products and services, located near Munich, Germany. Founded in 1981 by Joop A. Eggelaar, the company serves its customers with its more than 30 years of experience, and by providing real solutions. Through in-house training, the firm offers regular training courses on numerous topics, or can arrange specific employee training courses to suit specific needs.

Microtronic's customers are typically companies in need of products and services that serve microelectronic manufacturing, such as solderability testing, ultrasonic microscopes, circuit-board repair systems, welding systems, solders, and solder pastes. The firm offers centralized pricing to its customers with the added benefit of exceptional delivery times from its centralized European warehouses.

Microtronic offers an extensive range of products, including advanced systems for electronic quality control, research, repair, and manufacturing industries. Of these, the LBT-210 automatic and PC-controlled solderability tester is the most popular. Designed to check the integrity and quality of electronic solder joints, this cutting-edge system meets current industry challenges for electronic manufacturing. It can perform solderability testing using the two classical approaches: by solder bath or molten globule or solder. It also provides a new method to help improve production, using solder paste and a temperature profile. With this new method, a component is placed on printed solder paste and heated through the same temperature profile used in production. All force parameters and values during the heating cycle are monitored and analyzed. This is the only known method of simulating and qualifying the solder profile of an in-line production solder furnace in conjunction with different solder pastes and components.
Microtronic provides high-quality, advanced brands to customers, including this vacuum handling tool for small parts from Virtual Industries, Inc.


The company often faces the question "What is solderability testing and why is it important?" A solderability tester — or wetting balance — is a proven method for checking the mechanical and electrical quality of solder joints on components. These systems test components for solderability, preferably during incoming inspection. If the results are favorable, the components can be passed on to production. If the results are unacceptable, a lot of components can be returned to a manufacturer or distributor for replacement. Or, a manufacturer may order from another supplier at that point, to find a more reliable component source before production is disrupted. If components are not tested for solderability, there is the risk that a product will not pass functional test at the end of the production cycle because of bad solder joints. Defective manufactured units require expensive repairs or they cannot be reworked. Such rejects and the costs of product failures in the field can easily exceed the investment cost of a solderability tester.

This solderability testing is performed repeatably with today's PC-controlled measurement equipment. First, all component-relevant data and test parameters are placed into a screenmask. Next, a component for testing is clamped to a holder and fluxed. The holder is placed in the tester. The test is begun and the system's software collects all pertinent measurement data, showing the test curve together with the data of the standard norm chosen to determine solderability. Such testing should be performed with at least 10 sample components from the same lot, to provide a representative mean value.

Microtronic's LBT-210 solderability tester includes software that generates useful statistical information, including mean value and standard deviation. The system can be equipped with an optional camera to provide video of a test cycle that can be stored in memory with the appropriate test measurements and related data. The LBT-210 can also test under a nitrogen atmosphere, a function that can be switched on via software control. Nitrogen gas is commonly used to enhance the reliability of surface-mount-technology (SMT) components. And for those concerned with any residues from a test environment, as Microtronic's Managing Director Ernst Eggelaar points out: "Of course, we also included a scraper to clean the molten solder bath of any oxides before every test with the solder bath."

In addition to its own products, Microtronic specializes in providing advanced solutions to its customers that manufacture any type of electronics. Some of the brands it offers include EVS International, Virtual Industries Inc., SONIX, Akrometrix, AIM Specialty, APE, AVIO, AIT, IMI, Earthtronics, SEIT and many more. "Customers everywhere particularly value our service of assisting in the development of new products," said Eggelaar. "We focus on reducing potential problems during production and making testing as simple and easy as possible," he added.

Microtronic has finished an outstanding year in 2012, booking orders that exceeded initial expectations and expanding its workforce by 30 percent. In 2013, the company has already earned new business and is currently working on growing business further with some strong contracts. In addition, the company plans to roll out a new software version for its BLT210 Solderability Testers. As Eggelaar notes: "We had a big and successful presence at the SMT Hybrid Packaging Show and look forward to the rest of the year. We anticipate even larger growth by the end of 2013."
