Surface Mount Assembly ProcessOriginally, all PCBs were assembled by hand using only a solder iron. As technology progresses, components get smaller and more difficult to assemble by hand and the amount of components that may fit on a single board increases. Thus the need for auto assembly was developed.Required ElementsThe following are the required elements for auto assembly:Gerbers in 274-X (embedded apertures) including fabrication drawing.Part centroid text file with Reference Designators, ...

Flux Residues May Cause Harm On PCB Board

Flux residues have been the bane of reliability of PCB assemblies (PCBAs) from the first time they were used. However, it is necessary to use some sort of compound to reduce the oxides that form on the copper surface before soldering. circuit board Historically, activated rosin based fluxes were used to provide a surface for the solder to wet with. The problem with these fluxes is that they contained chlorine or bromine and remained corrosive after the soldering operation and would cause corrosi...

PCB Assembly and Production Process

PCB Assembly and Production Process- an overview of the PCB assembly process involved in building a surface mount technology (SMT) board using pick and place techniques. Within a printed circuit board electronics assembly / production or manufacturing process there are a number of individual stages. However it is necessary for them all to work together to form an integrated overall process. Each stage of assembly and production must be compatible with the next, and there must be feedback from t...

Printed Circuit Board Assembly

A PCB All about PCB assembliesMany modern products require the use of complicated circuits, so complicated that indeed it would be impractical to have them all individually wired, soldered and tested by hand. The solution to the problem is the Printed Circuit Board, commonly referred to as a PCB, which can make an extremely large and complicated circuit operate in an incredibly small and compact area. Ever seen the inside of a mobile phone or laptop that has been dissected? Remember that green ...

Flex & Rigid-Flex Capabilities

Rigid-flex circuitry provides a simple means to integrate multiple PCB assemblies and other elements such as display, input or storage devices without wires, cables or connectors, replacing them with thin, light composites that integrate wiring in ultra-thin, flexible ribbons between sections. In rigid-flex packaging, a flexible circuit substrate provides a backbone of wiring with rigid multiplayer circuit sections built-up as modules where needed. TTM produces flexible and rigid-flex circuits ...

How to Assemble Gore Mesh on the PCB

Printed circuit boards (PCB) are used in a number of electronic systems, including Global Positioning System devices. Some PCBs contain important information that can compromise a company's files and business operations if the information is obtained illegally. To prevent illegal tampering, a company protects its PCB by enclosing it with a metal enclosure with Gore mesh lining. If this lining becomes damaged, it can tell the company that someone had tampered with the PCB. Instructions 1 Lay t...

How to Troubleshoot the Process Steps for PCB Assembly

A printed circuit board forms an essential part of an integrated circuit. The main benefit of using a PCB to assemble a circuit is that you don’t need to wire each board-mounted component. PCBs have integrated conductive pathways, typically copper strips on the base, which conduct the current between the various resistors, capacitors, diodes and transistors. For this reason, PCBs are particularly suitable for self-assembly kits, such as guitar effects pedals. If you are having trouble with the...

Michelle Woolley shares examples of cleanliness issues found at the factory and in the field that were discovered during her work in failure analysis. The environment during the assembly process should be controlled for heat, humidity, and cleanliness. Depending on the product, a controlled clean room must be used to ensure cleanliness. For standard fine-pitch assembly and for consumer or non-critical business use, more standard conditions can be used. However, the cleanliness should exclude...

How to Create PCB Board

A printed circuit board (PCB) is platform used for connecting electronic components that also provides mechanical support. Once the PCB has been populated with electronic components, it is called a printed circuit assembly (PCA) or printed circuit board assembly (PCBA). A PCB requires a greater initial effort to design than wire-wrapped circuits, but is more economical for mass production. PCBs are produced in large quantities in a multistage industrial process.

Disadvantages of SMT PCB

Manual prototype PCB assembly or component-level repair is more difficult and requires skilled operators and more expensive tools, due to the small sizes and lead spacings of many SMDs. SMDs cannot be used directly with plug-in breadboards (a quick snap-and-play PCB prototyping tool), requiring either a custom PCB for every prototype or the mounting of the SMD upon a pin-leaded carrier. For prototyping around a specific SMD component, a less-expensive breakout board may be used. Additionally, s...
