Printed Circuit Board Assembly Technology

Right from their inception, assembly services have gained momentum and are considered as one of the most renowned services. Many companies are always on the look out for best assembling technology and services and manufacturers give the best of their services.But before proceeding, let us first know about a PCB Assembly-When electronic components are attached to a PCB, it is referred to as Printed Circuit Assembly. It is done only after a Circuit Board Assembly has been created completely. Various kinds of techniques are available to attach electronic...

Automated inspection in printed circuit board assembly (PCBA) manufacturing

Visual inspection has long been a necessary method of quality control in Printed Circuit Board Assemblies (PCBA) manufacturing. The characteristics of electronic assemblies have changed substantially over the last decade. Todays high lead count, fine pitch SMT components are becoming even more difficult for humans to inspect at the same time automated...

Which Laptop battery is right for you?

The short answer is: “Whichever type fits your laptop.”Laptop batteries vary according to the model and type of laptop computer for which they’ve been designed. All laptop batteries do, however, share some common characteristics that differentiate them from regular household batteries:• Laptop batteries are rechargeable• They are composed of...

Outer Layer Circuit Formation

This section describes the processes used to create the printed circuit design on the two outer layers of the panel.1 RESIST APPLICATION OPERATIONSThe types of resist and application methods used by the PCB industry for Outer Layer Circuit Formation are the same as the Inner Layer Circuit Formation.2 EXPOSURE UNITSThe resist that has been applied to the outer layers of a circuit board panel is selectively exposed to UV light using photo design tools and electric Exposure Units similar to those for inner layer circuit formation. However, the outer...

Printed Circuit Board Manufacturing

Printed circuit boards are electronic circuits created by mounting electronic components on a nonconductive board, and creating conductive connections between them. The creation of circuit patterns is accomplished using both additive and subtractive methods. The conductive circuit is generally copper, although aluminum, nickel, chrome, and other metals are sometimes used. There are three basic varieties of printed circuit boards: single-sided, double-sided, and multi-layered. The spatial and density requirement, and the circuitry complexity determine...

Printed Circuit Board Manufacture

The manufacture of a multi-layer circuit board typically starts with preparing the board laminates. Each laminate has a core of fiberglass-reinforced polymer resin, with both sides of the core laminated over with copper foil surfaces. The resulting laminate is then baked, to cure and stabilize the polymer core. Subsequent processing etches the copper...
