In the fields of Electrical and Electronic industry, the vast pacing technology has made it hard for electronic manufacturers to face the demand of keeping abreast with the rising technologies. Also, the mounting trends of small packaged gadgets like mobile phones and hand held computers have added to the burden of these electronic component producers to develop lower cost, smaller size and higher performance levels with regard to passive components.
In regard to this, a huge pressure is also exerted on the components designers to alter the structure of Multi layer Ceramics in the EMI filter segment to achieve Insertion Loss performance levels similar to those of board mounted devices.
EMI filters are selectively designed to decrease the reception of unnecessary signals. They are manufactured with combined capacitors and inductors using varieties of impedance characteristics. The multilayer capacitor or ceramic chips are included in these multilayer ceramic filters. These chips are the most popular and commonly used chips in the field of capacitors industry.
Another in demand electronic part is the RF connector. This electronically designed connector is used with radio frequencies in the multi-megahertz range. They are typically manufactured to be utilized with coaxial cables to keep the shield that coaxial design renders. There are also better models that are used to minimize the alteration with transmission line impedance and connection.
Laser welding is a part of the breakthrough since these are generally for miniature type of welding jobs. It uses laser beams that have many advantages like narrow and deep welds because it has concentrated heat source. Laser beams are also utilized in the automotive field due to its fast and high volume usage.
Laser beam in welding allows high power density that in turn yields localized heat affected zones to permit high heating and cooling rates. Typically, the size of the laser spot can be between 0.2mm and 13mm.
