SMT Repair and Inspection Equipment

Equipment unique to surface mounting includes inspection and repair / rework equipment. Inspection equipment for surface mounting in electronics has not matured yet. There are two main types of automated inspection equipment on the market: x-ray and laser. However, most electronic companies depend on visual inspection at 2 to 10X, using either microscope of magnifying …

SMT Solvent Cleaning Equipment / Machine To Clean Flux with Water

After soldering, the electronic assemblies must be cleaned to remove excess solder flux. The subjects of flux and cleaning are closely intertwined. The selection of solvent and cleaning equipment depends of the flux used and the cleanliness requirements.

The cleaning process has received considerable attention because of efforts to eliminate chlorofluorocarbons (CFCs) and other ozone depleting chemicals. CFCs were …

SMT Solder Paste Screen Printer Machine for Solder Paste Screen Printing

A Solder Paste Screen Printer for SMT is needed to screen solder paste onto the printed circuit board (PCB) before placement of surface mount components.

Solder Paste Screen Printer for SMT have been widely used in electronics by the PCB industry for screen solder mask. This equipment / machine has also been extensively used in the hybrid industry for screening …

SMT Dictionary – Surface Mount Technology Acronym and Abbreviation

SMT (Surface Mount Technology) is a packaging technology in electronics that mounts electronic components on the surface of a Printed Circuit Board / Printed Wiring Board (PCB / PWB) instead of inserting them through holes of the board. SMT or Surface Mount Technology is relatively new technology in electronics and provides state-of-art, miniature electronics products at reduced weight, volume and …

Surface Mount Design Considerations in SMT & CTE Mismatching

There are many design issues that must be settled before a surface mount technology design or packaging direction is selected.

System analysts start with determining product needs in the marketplace. Therefore, the designer must look at the proposed product from the systems point of view. Great devices on printed circuit boards do not sell in the marketplace. Products sell. Therefore, …

Types of Surface Mounting in SMT

Many electronic components are not yet available in SMD for surface mounting. Due to this reason, SMT must accommodate some through-hole components. Therefore the term “Surface Mount Assembly is incomplete”. Surface mount components, active and passive, when attached to the substrate, form three major types of SMT assembly – commonly referred to as Type I, Type II and Type …

SMT Soldering and PCB Assembly Techniques

In Electronics, SMD soldering and SMT Assembly Techniques are different from that of thru-hole soldering techniques. SMD soldering or Surface Mount Technology assembly needs different SMT Equipments and greater experience and expertise.

Surface Mount Circuit Boards have flat tin-lead or gold-plated copper pads without any hole. These traces are called solder pads. Semi-solid solder called solder paste consisting of very …

SMT in Assembly Line for Manufacturing and Production of Surface Mount Technology PCB Assembly

For successful implementation of Surface Mount Technology (SMT) in the assembly line for manufacturing and production, the first order of business for management consideration is to obtain a clear outline of the outstanding technical issues. Then an SMT team consisting of a selected group of engineers / individuals from all functional organizations should be assembled to address those issues. The …

Benefits / Advantages of Surface Mount Technology (SMT) Over Through-Hole

Surface mount components are small and can be mounted on either side of the PCB and have gained widespread usage in electronics. The benefits of SMT or Surface Mount Technology are available in both design and manufacturing.

Design Benefits of Surface Mount Technology

Among the most important design-related benefits are significant savings in weight and real estate and electrical …
