A Quick Guide to Samsung Galaxy S4 Printed Circuit Boards

Established in 1938, Samsung manufactures electronics, including circuit boards and cell phones. Samsung offers replacement parts for its electronics. It released the Galaxy S4 smartphone in 2013, and this phone is capable of LTE wireless signals as well as NFC communications.

Most electronics use printed circuit boards (PCB), wire wrap, or point-to-point construction. You will also see a PCB referred to “printed wiring boards” or “printed wiring cards.” A PCB helps to route power and signals within a physical device. Various electronic components attached to the PCB surface using solder, a metal that conducts electricity and acts as a mechanical adhesive.

In early forms of PCBs, components attached to perforated or perf board. Updated PCBs use a solid board, usually a copper base. The printed portion of the name refers to a silkscreened layer that covers the copper's solder mask. The circuit board has a guide of letters, numbers, and symbols printed onto its surface to make assembling the attached electronic components easier. These components can be comprised of single-sided, double-sided, or multi-sided layers.

The phone's manufacturer offers circuit boards for cell phone models, including the Samsung Galaxy S4, Galaxy Note, Samsung Galaxy S, and the HTC one. You may also be able to obtain generic or unbranded PCBs to fit this phone.

This S4 board features connections that power all the cell phone's features such as the simultaneous dual camera operation, the rear camera, the full HD Super AMOLED home screen, and air gesture.

• Avoid exposing your smartphone to dirt, heat, or moisture to make your S4 circuit board last longer. Instead, leave your device in a dry room when you shower.
• Avoid leaving your Galaxy S4 in a hot car. Store your cell phone inside a slipcase in your jacket pocket or purse.
• Keep your smartphone's exterior clean. Once per week, blow out the inside of your Galaxy with compressed air.

Normal component aging can cause failure of capacitors, resistors, drivers, or other parts. Age, heat, or exposure to the wrong voltage can all cause power component failure. A power surge can cause trace damage to conductive pathways. Physical damage to the Galaxy phone like a drop to a hard floor or cement surface can damage the soldered connections or the board itself.
