BGA Soldering Quality Detection Techniques by X-Ray Imaging

Introduction:BGA is a typical high-density packaging technology. Its characteristics are that the chip pins are distributed under the package in the form of spherical solder joints, which can make the device smaller, more pins, larger pin spacing, higher assembly rate of finished products and better electrical performance. Thus, the application of this kind of packaging method is more and more popular with the market.Currently, BGA soldering quality detection methods are very limited. Common det...

Analysis of the Methods of PCB Interconnection

Introduction:Electronic components and electromechanical components have electrical contacts, and the electrical connection between two discrete contacts becomes an interconnection. The electronic devices must be interconnected according to the circuit schematic diagram in order to achieve the predetermined function.As a part of the whole machine, a PCB generally cannot constitute an electronic product, and there must be the problem of external connection. For example, electrical connections are...

Materials of the High-Density Flexible Printed Circuit Boards

Introduction:The basic materials of high-density flexible PCB are substrates, conductors and cover layers (cladding). Substrates and conductors are usually laminated together to form copper clad laminates.Materials of Conductors:One of the main ways to achieve HDI flexible printed circuit boards is to use the thin, fine grained and low-profile copper foils. The standard copper foil used in conventional flexible printed circuit boards has always been RA foil, usually with a thickness of 1OZ (35um...

Material Requirements of High-Density Flexible PCB

Introduction:Recent market trends show that high-density interconnection technology, or HDI, is growing more than twice as fast as conventional lines. HDI circuit usually means that the pitch of the circuit is less than 8mils (200um) and the aperture is less than 10mils (250um). It is estimated that the most significant applications driving the growth of HDI flexible printed circuit boards are in mobile communications and computer devices like PDA. Other high-growth applications include tape fle...

How to Read & Understand a Circuit Diagram

Introduction:Today, I would like to ask you a question, when you are just a beginner in the PCB field, whether it is the same as me, every time I see the circuit diagram, I think "oh my god! Am I a fool? If not, why can't I read any of these circuit diagrams and why on earth am I taking this course?” I think a lot of people will be confused as me, when we face the crisscross dense lines but do not know how to start. In fact, circuit diagrams are easy to understand and easy to use. The k...

Suitable Temperature Curve of Lead-free Solder

Introduction:Alloy, , is the best solder in the reflowing process. Compared with the traditional solder, it has two disadvantages in terms of manufacturability as following:1) The melting point is high. It has a melting point of about 217 degrees Celsius and a complete melting temperature of 235 degrees Celsius. Therefore, we must raise the manufacturing temperature in the manufacturing process, otherwise it will cause a series of adverse consequences.2) Wettability is slightly worse. Th...

Advantages and Disadvantages of Surface Mounting Technology

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...
