Something You Must Know about Surface Mount Technology (SMT)

Introduction:Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In industry, it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board, with the through-hole technolo...

Impedance Control of PCB

As circuit design becomes increasingly complex and high-speed, how to ensure the integrity of various signals (especially high-speed signals), that is, to ensure signal quality, has becomes a problem.At this point, will take advantage of transmission line theory to analyze. Control signal characteristic impedance matching becomes the key point. Non-strict impedance control will cause considerable signal reflections and signal distortions, leading to design failures. Common signals such as PCI bu...

How Printed Circuit Boards Are Made

A printed circuit board, or PCB, is a self-contained module of interconnected electronic components found in devices ranging from common beepers, or pagers, and radios to sophisticated radar and computer systems. The circuits are formed by a thin layer of conducting material deposited, or "printed," on the surface of an insulating board known as the substrate. Individual electronic components are placed on the surface of the substrate and soldered to the interconnecting circuits. Contact fingers...

IPC Standards in Printed Circuit Boards

Quality standards are highly important when manufacturing electronic printed circuit boards. PCBs are often produced in bulk, so any kind of fault that would hamper the effective operation of one PCB could affect dozens or even hundreds of them. At the same time, when you make any kind of purchase, you expect a certain level of quality. What is the IPC?IPC is a global trade association for the electronics industry. The ‘Institute for Printed Circuits’ (IPC) is the association connecting ele...

How to Make a Negative Resist PCB

A printed circuit board consists of a substrate upon which copper tracks connect electrical components. The copper tracks on a PCB can be very tiny -- 1 millionth of a meter -- which allows many electrical components to be combined into a small space. PCB boards are typically made using a process known as photo-lithography. During this process, light is shone through a stencil and the exposed parts of the substrate become chemically changed. In negative resist photo-lithography, the exposed part...

How to Trace a PCB on a Projection TV

Traces on printed circuit boards (PCBs) are the electrical circulatory system inside a projection television. Fully functioning capacitors and resistors on a computer's circuit board may be completely functional, but fail to work correctly due to a bad trace. Repairing a bad trace is a matter of understanding what one looks like, then tackling the repair itself. Instructions 1 Locate the broken trace with a magnifying glass. The trace may also appear scorched or burned. 2 Cut repeated shallo...

How to Convert PCB to Gerber

Engineers use PCB files to design printed circuit boards for various electronics. PCB files are are only a part of the design process. After an engineer completes a design for a printed circuit board, they will send it to a manufacturer. The equipment that prints these circuit boards cannot read PCB files, and instead relies on the Gerber file-type. Before engineers send off their circuit board designs to manufacturers, they must convert their PCB files to the Gerber file-type. PCB files come in...

How to Control Radiated EMI Through PCB

All electronic devices, such as cell phones and televisions, contain one or more Printed Circuit Boards (PCBs). PCBs have electronic components that are connected together through thin copper traces. When such a PCB is operating, electrical currents constantly travel between different components through copper traces. These changing currents produce Electromagnetic Interference (EMI), which can affect the performance of the circuit and of any other electronic device in the vicinity of the circui...

PCB Via Types

The printed circuit board, or PCB, is the flat surface containing all the wiring and components of electronic devices. PCBs are layered in order to increase capacity, with small openings known as vias between the layers. Vias provide more connections which translates into a more effective PCB. Different types of vias are used, with each one serving a different purpose. Standard ViaA standard via, usually referred to as just a via, starts at one end of a multilayered PCB and continues all the w...

How to Clean Flux From PCBs

Flux is used when soldering electrical components to a printed circuit board. Depending on the components and type of solder used, flux is applied to solidify the electrical connection. The residue left by applying flux paste, or solder flux is usually removed to prevent inhibition of printed or etched wiring, and to avoid obscuring other components. Removing flux from a PCB is a simple task. Instructions 1 Dip a clean toothbrush in isopropyl alcohol or acetone. Flick away excess by flipping y...

How to Deal With PCBs When Recycling Electronics

Printed circuit boards (PCBs) are integral components of many electronic devices, typically composed of a dry film laminated onto copper foil with a fiberglass base. Manufacturers usually install them as plug in parts, so when they burn out or become obsolete, you can replace them. Because they contain potentially harmful chemicals and metals, the EPA classifies them as toxic or "special" waste. Here's how to dispose of them safely. Instructions 1 Recycle PCBs by finding a local facility that ...

PCB failure: Electrical overstress assessment

Many times, when a component supplier is asked to do an analysis on a failing component, the conclusion is electrical overstress (EOS). Unfortunately, this conclusion does not tell the user much about the cause of failure. EOS can be caused by an excess of voltage, current, or power. For best results, this conclusion should be followed up by further analysis to determine if the cause was excessive voltage, excessive current, or a combination of voltage, current, and power. The diagnosis of E...

Dry Film Imaging of PCB

The photopolymerization characteristic and the convenience of dry film photo resist make it useful for image transfer in PCB fabrication. Ideally, the dry film imaging process should be done in a clean room with amber light illumination. Dust is a killer in fine line construction. Hence, a clean room is needed for PCB fabrication with fine line structure. For example, a class 10,000 clean room can be used up to 5 mil (0.127mm) line width. Dry film is available in a range of film thickness from ...
