This process applies a unique identifier to each bare Printed Circuit Board (PCB) to help with traceability during manufacturing and once in the field.
Since 1981, Electronics Manufacturing Sciences has provided the knowledge and hands-on support that enable electronics manufacturers to achieve best-in-class reliability and efficiency. Our clients include the world's largest corporations and many companies still in the startup phase. We focus on soldering because it is both the core process of electronics manufacturing and the most misunderstood.
The Science of Soldering© is the only soldering training and certification that teaches soldering for what it is — a scientific process, not a random collection of erroneous hunches and arbitrary rules.
Widely regarded for decades as one of the foremost North American electronics assembly authorities, Jim founded Electronics Manufacturing Sciences in 1981 to teach that science of soldering in terms that everyone in the factory could understand and use. "The point of Science of Soldering© was and is to make perfect soldering easy and inexpensive," Jim explains. "And it succeeds splendidly.
Many thousands of engineers, operators, technicians and managers worldwide have attended Science of Soldering© classes in their companies. Jim’s soldering workshops have also been featured in NEPCON professional development programs throughout North America and Europe and Georgia Tech Professional Development."
Electronics Manufacturing Sciences provides education and certification services that go beyond the usual industry requirements. Our methodology includes our own Science of Soldering© education that provides important techniques for product reliability and workplace efficiencies that are not offered by other courses. The great strength of Science of Soldering© lies in its effective communication with individuals of all educational levels. The curriculum is thorough but presented in ways that make it easy to understand by anyone, even those who haven't completed high school. student's ability. We developed demonstrations, hands–on exercises, and audio–visual presentations that make these critical lessons clear to everyone regardless of formal education.
Trained Gearbox Europlacer personnel will train local engineers and participants in the Science of Soldering. Upon successful completion of the training, participants will then receive certification from EMS inc, (Florida, USA)
The Science portion combines demonstrations, experiments and troubleshooting of a unique soldering process problem. This is followed by exercises in which the lessons are applied to specific manufacturing applications such as terminals, through–hole and surface mount assemblies. Industry high reliability requirements are taught throughout. Although the final curriculum can be modified to meet the client's special needs, the usual curriculum consists of:
1. The Core Science
Wetting forces Chemical reactions Intermetallic bonds
2. Clean Surfaces
Definition and importance Contamination Oxides
3. Flux
Defined Types and attributes Acidity, ionic contamination and effects on reliability The real definition of no–clean flux Selecting fluxes suitable for high reliability applications
4. Solderability
Definition and importance Solderability of different component and PCB surfaces Implications of lead–free component finishes Scientific solderability management
5. Solder
Defined Alloys (leaded and lead–free) Mechanical properties (ductility and tensility) Lead–free solder differences and techniques
6. Heat
Why heat is needed How much heat is needed Failure modes from overheating Scientific heat control and elimination of damage during hand soldering
7. Soldering vs. Welding
Definitions Significance of surfaces that melt during “soldering” vs. surfaces that do not melt (the overlooked lead–free issue) Uses of soldering and welding in electronics assembly
8. Troubleshooting
Using the Science of Soldering© Recipe
9. Prevention of Heat Damage in Hand Soldering
The Electronics Manufacturing Sciences Solution ."
The hands-on soldering exercises depend on the components actually used in the client's products, including some or all of the following: Wiring methodologies and multi–terminal exercises: turret terminals, bifurcated terminals, eyelet terminals, cup terminals Through–hole soldering: IC's, transistors, capacitors, resistors; includes heat sink and solderability problem Surface mount soldering: resistors, transistors, MELFs, PLCCs, SOICs including fine pitch and J–leads, quad packs Repair techniques (through–hole and surface mount)
Throughout the entire course, the commonly accepted workmanship requirements are referenced and explained in context. This final stage sums up the requirements and verifies student comprehension
Soldering irons operate at 300F° or more above the temperature that damages internal bonds of modern components like I.C.s., changes the value of resistors and delaminates capacitors Improper use of soldering irons is today's number one cause of electronics systems failures. (For more information, go here.)
Many companies needlessly buy expensive constant temperature irons costing hundreds of dollars. Others waste engineering time calibrating iron temperatures. Neither approach prevents heat damage. An improperly used constant temperature iron causes just as much damage as an improperly used iron with erratic temperature. We developed a simple, easy, foolproof technique that keeps component temperature below 500° even with an iron temperature of 800°. (No, we don't recommend using 800° irons for most purposes. But a technique that works for an 800° iron works just as well at normal iron temperatures.)
The Science of Soldering© technique works with any soldering iron, requires no additional tools or materials and takes no additional time than the technique used by your operators now. And only teaches this critical technique.
