Invented in 1936 and first utilized in radios around 1942, the Printed Circuit Board (PCB) is now found in almost every electronic device around the world. The use of Printed Circuit Board became popular during the 1950s. Previous to using circuit boards, components in electronic goods had to be hand soldered with wires, a method that did not lend itself to automation. Designing And Making Of Printed Circuit Board:The Printed Circuit Board is...more
Electrical appliances & equipment requires electrical testing and tagging to guarantee safety of the user. Test and tag in Melbourne is a testing method is undertaken to ensure that electrical equipment does not pose any risk to the user. Before the appliances hit the market, all the equipment undergoes the assessment process like portable appliance testing, appliance testing, etc. Many overlook the importance of electrical testing and tagging of...more
These days many toy manufacturers are focusing on educational usefulness of toys even though right from the olden days, toys are known to nurture the minds of kids by offering them entertainment and ability to discover new things. Parents ultimately want the best for their children and most of them are nowadays aware of the fact that learning toys are helpful not only in expressing their love, but also enables the child to learn new things. It has been accepted by child psychologists that a child begins his/her development process even as an infant and every item presented to the child will have an effect on his/her development. Moms are generally aware of the requirements of their children and they should also carefully select the toys irrespective of its type for that matter.It is essential to procure toys that can enable the child to improve his/her control and co-ordination. Earlier, it was believed that electronic toys are meant only for grown up kids since the market for this type of toys was limited. However, nowadays, these toys are available for children of different age groups and even there are toys for children in the age group of 3 to 6 years. For children of this age...more
Laboratory drying ovens are used in several applications in a laboratory. These are used in laboratories to give unusual thermal applications which are used for wide-ranging lab work and processing. Apart from their use in laboratory they are even used for industrial purposes such as in pharmaceuticals, electronics and metal processing. These...more
What is Terahertz?Terahertz (THz) are electronic waves which operate at a frequency within the Terahertz spectrum. Their spectral fingerprint rests between microwaves and infrared, invisible due to being out of the visible light spectrum, and the least explored region of the electromagnetic spectrum. Until the 1990s, producing and detecting...more
Laboratory shaker are devices that are used in laboratories to mix liquids. In a laboratory, there are several equipments that are used for various research and development projects as well as for handling and preparing of chemicals. So, laboratory shaker are used for carrying out these experiments and for mixing or stirring liquid.Mixing and stirring are extremely important in performing different kinds of experiments, as they act as catalyst which is used to promote the molecular reactions of chemical substances. How frequently and fast a laboratory shaker mixes the chemicals, is what determines its efficiency. There can be different types of shakers some may be slow in speed and some may be fast, depending upon the material that needs to be mixed. The most popular type of shakers that are used in a laboratory is magnetic stirrer. Laboratory shakers has been replaced by the Magnetic stirrer as it is provided with the latest and advanced technologies. Laboratory shakers are double walled convection units, the outer body of this is made up of thick PRPC sheet and the inner chamber is made of heavy gauge stainless steel of SS-304 grade. The gap between these two walls is filled with...more
Virtually every electronic device relies on printed circuit boards, commonly referred to as PCBs. Without them, electronics wouldn't be able to conduct the flow of electricity properly and the device wouldn't function. The PCB is kind of like the...more
