PCB Failure Analysis Identification and Testing of Defects. From cheap toys and smartphones to sophisticated computers and radar detector systems, printed circuit boards (PCB) are critical components for today’s electronic and industrial technology.Almost every electronic device has one of these self-contained modules of complex interconnected electronic components, which include resistors
· First of all, we boil it down to two capacitor types Polarized capacitor. Non-polarized capacitor. The difference between a polarized capacitor and a non-polarized capacitor is that the polarized capacitor has a positive and a negative side. So it must be placed with the positive pin where the most positive voltage is.
· Step 1 To find the voltage rating of the MOV, allow for 20% headroom to account for voltage swell and power-supply tolerances 24 V dc × 1.2 = 28.8 V dc. Given that no varistors have a voltage
The type of solder used in electrical bonding contain different materials with the most common one composed of 60% tin and 40% lead, thus the name 60/40 solder. There are two dominant types of solder. • The lead-based solder • The lead-free solder. Next, wne‘ll take a closer look at the solder used for the board and the differences.. 2. Board Best Solder Category

· The processing of e-waste typically begins with a manually intensive dismantling phase, during which circuit-board components and the lithium battery are removed for recycling elsewhere . The PCBs are subsequently graded according to their metal plastic ratio and shredded, typically into 1.0 cm 2 pieces. The shredded PCBs need to be separated into metallic (ferrous and non-ferrous), and non
· A finger on the board nearby may help to notice too much heat. Try to err on the side of irons that are less powerful than you think you might need. A 30-watt iron will be adequate for most electronic work. Practice soldering is a very good idea. If working with a double-sided circuit board check both sides for good solder joints.
· Read on to find out how to choose an external drive for better peace of mind. Storage capacity Arguably the most essential specification to consider
An RCD monitors the earth leakage current in a circuit. It is constructed from coils of wire wound around a ferrite toroid core, one for each live conductor of the circuit protected. When a current imbalance between live conductors is detected, a voltage will be induced in
Therefore, the best advice on the type of solder to use as the best circuit board is any solder that is lead-free and with a flexible resin core. If you decide to opt to check via the manufacturer website, look for a datasheet that has all the details of the standard solder, where testing was done to prove that what you choose to buy is the recommended solder for your type of circuit board .
· Common materials for recycling include tires, bottles, paper towels and aluminum cans et al and the niches available in the recycling industry are metal recycling, plastic recycling, electronic recycling, water recycling, oil recycling, glass recycling, furniture recycling, garbage recycling, tire recycling, construction waste recycling, paper recycling, battery recycling, cartridge recycling
The Industry Council for Electronic Equipment Recycling (ICER) was founded in 1992 by a consortium of companies including names such as Boots, CL, IBM, BT and the BPF. It aims to oversee the development of recycling facilities for electrical and electronic equipment in the UK.
When choosing a suitable replacement transistor for use within an electronic circuit, there are several stages that must be considered when making the choice. These can be progressed in a logical order to narrow down the choice and enable the best alternative for the replacement transistor to be made.
Electronic Recycling Process. The recycling process varies as there are different kinds of electronic devices. The metals and other substances suitable for recovery and the technologies used to reclaim them also make a difference. The process starts with the collection and transportation of electronics to the recycling area.

· Recycling of printed circuit boards has been driven by the content of precious and other metals and their potential for recovery and sale into the metals markets. Table 2 shows that gold, palladium and silver are in significant concentrations in printed circuit boards with concentrations up to 0.1 wt% gold, 0.03 wt% palladium and 0.3 wt% silver.
How to Extract Gold From Electronics In this Instructable, I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy, but the chemicals used are very dangerou

Tŷ Hafan has partnered up with A & LH Environmental to allow supporters the opportunity to responsibly clear out tech, surplus IT and electrical equipment whilst raising funds for our hospice. A & LH specialise in safe and ethical removal and recycling, re-use and disposal of IT and electrical equipment.
· Many electronic devices contain a small amount of gold, especially on the circuit board. This is because gold is a highly efficient conductor (better than copper) and it does not corrode, ensuring therefore that no interruption occurs in transmitting voltages and currents needed to run the device.
· PCB board recycling business is one of the most popular e waste recycling business now in the world. If you also plan to start the PCB board recycling business, then there are some preparations that you need to make first, like collecting enough raw materials, learning about product selling market and buying a suitable machine.

Zener Diode Voltage Regulator. A Zener Diode is an electronic component which can be used to make a very simple voltage regulator circuit. This circuit enables a fixed stable voltage to be taken from an unstable voltage source such as the battery bank of a renewable energy system which will fluctuate depending on the state of charge of the bank.
