PCB assembly Defect Coverage Using Automated Optical Inspection (AOI)

PCB assembly Defect Coverage Using Automated Optical Inspection (AOI) Automated Optical Inspection (AOI), which is an automated visual inspection of a Printed Circuit Board (PCB), provides 100% visible component and solder-joint inspection. This testing method has been in use in PCB manufacturing for almost two decades. It plays a critical role in ensuring that there are no random faults in the assembly. The technique, which uses lighting, cameras, and vision computers, is incorporated in the assembly process to guarantee the highest possible quality throughout each phase of a product’s life cycle. The method enables fast and accurate inspection and can [...]

Material Selection for High frequency PCB Fabrication

We mostly use high frequency laminates in high frequency PCB. However, these are often difficult to fabricate. Because they must maintain the thermal heat transfer of the application due to the sensitivity of the transmitted signal. So, we need special materials for high frequency PCB manufacturing. When you are selecting a material for High frequency PCB, you must keep the following in mind. Dielectric constant It is the ability of a material to store energy when we apply an electric field. However, it is a directional property which means that it will change with the axis of the material. So, [...]

Printed Circuit Board industry accelerates transfer to China

The Printed Circuit Board industry moves eastward and the mainland is unique. The focus of the PCB industry is constantly shifting to the Asian region, and Asia's production capacity is further transferred to the mainland, forming a new industrial structure. With the continuous transfer of production capacity, mainland China has become the region with the highest PCB production capacity in the world.   Applications such as data centers will increase HDI board demand, and FPC will have broad prospects. Data centers are moving in the direction of high speed, high capacity, cloud computing and high performance, and construction demand is [...]

SMT assembly Processing / Patch Processing Basic Process Elements

The basic process elements of smt assembly processing / patch processing: Silk Screen (or Dispensing) --> Mounting --> (Curing) --> Reflow Soldering --> Cleaning --> Testing --> Rework Silk screen: Its function is to print solder paste or patch glue on the pad of PCB to prepare for soldering of components. The equipment used is a screen printing machine (screen printer), located at the forefront of the SMT production line. Dispensing: It is a glue that drops the glue to a fixed position on the PCB. Its main function is to fix the components to the PCB. The equipment used [...]

Electronics assembly manufacturing–Why Use Reflow Soldering?

Electronics assembly manufacturing Reflow soldering allows for the simultaneous processing of multiple connections. This prevents the disconnection of wires while you are soldering their neighboring wires. Reflow Soldering also improves the quality of resulting PCB Electronics assembly and offers many other benefits such as, Improved wettability of solder joints and surface mounted components. Improved solderability of a large variety of electronic components. Enhanced joint integrity for crucial electronic applications. Reduced board discoloration. Elimination of charred flux residues on heating elements and boards. Reduced formation of white haze from the oxidation of rosin or tin flux Optimized performance of low-residue and [...]

Flex Circuits board Fit Where Cables Cannot

Flex printed circuits board can provide several obvious advantages over conventional ribbon cables in certain applications. For example, a flex circuit can span between a board and a connector on a bulkhead several inches away at a right angle in the same plane as the board. That’s not feasible with a ribbon cable. A flex circuit can be formed in complex shapes in three dimensions with branches to multiple connectors, which would be impossible to achieve with a ribbon cable. Moreover, flex circuits can be interfaced with rigid boards without the relatively tall and bulky connectors flat cables require, or [...]

Risk Factors for Flexible Printed Circuit Boards

  Flexible Printed Circuit Boards (PCBs) are perfect for the current electronic needs. They are lightweight, can be compact, and with proper design, can offer extremely robust solutions. However, although flexible PCBs can bend, they still must fulfill some specific requirements that traditional rigid PCBs do not. The design process of flexible PCBs must consider the number of layers, placement of features, circuit architecture, and materials. The designer must also consider the frequency of circuit flexure, and the method of formation of the bend, including the bend tightness and the degree of the bend. The designer can take advantage of [...]
