Thermal Profiling: A Practical Approach to Reflow Profiling

knowledge and practice. Moreover, it is an art. Reflow soldering profiling warrants more discussion in detail. Thermal Profile A thermal profile is a time versus temperature graph of the soldering process. Profiling is the process to determine the proper time duration and temperature a PCB assembly (PCBA)

Effect of Silicone Contamination on Assembly Processes

Silicone contamination is known to have a negative impact on assembly processes such as soldering, adhesive bonding, coating, and wire bonding. In particular, silicone is known to cause de-wetting of materials from surfaces and can result in adhesive failures.

RULES FOR WORKING WITH 0201s AND OTHER SMALL …

The most effective solder paste for 0201 components is type 4 or sphere-sized paste; pair the paste with water-soluble flux for cleaning. SOLDER SELECTION The small size of the solder pad and the 0201 component causes the PCB to form a bump, making the component tilt and slide off the pad. Tilting can best be prevented by using a PCB circuit

SOFTWARE DESIGN TECHNIQUES

DESIGN METHODOLOGIES - 2 A more methodical approach to software design is proposed by structured methods which are sets of notations and guidelines for software design. Two major rules of this method Programs were to be broken into functions and subroutines There was only a single entry point and a single exit point for any function or routine.

SuStainable tropical building deSign

2.1 paSSive deSign ‘Passive design’ is design that works with the environment to exclude unwanted heat or cold and take advantage of sun and breezes, therefore avoiding or minimising the need for mechanical heating or cooling. Passive design in the tropics means designing a building to make the most of natural light and cooling
