Through-hole packages

There are two methods of placing components on a printed circuit board (PCB). The first one is Through-Hole Mounting (THM) and the other one is specified as Surface Mount Technology (SMT). At EPR we use SMT as well as THM. Both methods have their advantages and disadvantages.

3D Printed Electronics. 3D printing technology is probably one of the most exciting technological innovations in recent years. From 3D-printed organs to firearms and ammo, 3D printing has accomplished some incredible things in a variety of industries. The PCB industry is no different.

Surface-mount technology (SMT) is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD).

Benefits of Surface Mount Technology in Manufacturing The important advantage of SMT in manufacturing includes reduced board cost, reduced material handling costs, and a controlled manufacturing process. Routing of traces is reduced, the size of the board is reduced, and number of drilled holes are also reduced.

When the PCBs are mounted, the leads of components need to be sent, shaped or cut short, so that the whole process is shortened and the production efficiency is improved. This is the reason that the processing cost of the same functional circuit is lower than that of through-hole interpolation.

A surface-mount device or SMD is an electronic device for which the components are mounted or placed directly onto the surface of the PCB. Surface-mount technology, or SMT, is the name of the method used for producing an SMD.

There are two main methods for mounting components onto a PCB: through-hole mounting and surface mounting. While surface-mount devices (SMDs) are secured only by solder on the surface of the board, through-hole component leads run through the board, allowing the components to withstand more environmental stress.

VayoPro-SMT Expert is an essential tool for intelligent & fast programming. It converts CAD/Gerber/BOM data, corrects parts angle/polarity/offset intelligently, generates placement program/recipe/feeder list/assembly drawing document, converts existing program/recipe to different placement platform.

SMD vs SMT What is the Difference? The difference between SMD and SMT is that SMD (surface mount device) refers to an electronic component that is mounted on a PCB. In contrast, SMT (surface mount technology) relates to the method used to place electronic components on a printed circuit board.

Surface mount technology (SMT) operators monitor and maintain any equipment used in establishing SMT electronic circuits. The task of SMT operators involves SMT machine operation to mount electronic components onto the circuit boards. Hand assemble and run diagnostic tests on various electronic components.

SMT Operators handle equipment used to develop circuits with surface mount technology (components are mounted directly on circuit boards). Usual duties listed on a SMT Operator example resume are placing components on circuit boards, calibrating equipment, following production schedules, and performing quality control.

PCB assembly process overview. The various stages in the PCB assembly process including adding solder paste to the board, pick and place of the components, soldering, inspection and test. All these processes are required, and need to be monitored to ensure that product of the highest quality is produced.

Surface mount soldering is the process of creating circuits using surface mount technology (SMT) components that are mounted directly onto the surface of printed circuit boards (PCBs). The manufacture of PCB circuits via surface mount soldering was a key breakthrough that makes this possible.

Through-hole technology (also spelled “thru-hole”), refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or …

SMD stands for Surface Mount Device and they are components that you solder on the surface of a circuit board. Let me guide you through how to do SMD soldering with a soldering iron. (The most common method to solder these components is using an oven. Also called SMD Reflow Soldering)

Yes, you can solder without flux. While it is helpful in the process of soldering as the flux helps break down the oxides on the metal, it is not needed. Also, most solder nowadays come with a rosin core which does the job of flux helping breaking down oxides.

hand soldering smd isn’t difficult, but it is tedious. well let’s see, not so good iron, not so good solder, wrong flux = no mystery there. use this flux http://amzn.to/1qHs0We don’t use no clean. flux is going to be messy but it makes soldering work.

Clean the tip of the soldering iron and apply just a tiny bit of new solder to the tip. Now hold the SMD part in place with tweezers and touch one terminal with the soldering iron tip. The joint should flow together nicely. Now that the part is fixed in place solder the other side.

1. Use a pair of tweezers to hold the capacitor and pull gently.
2. Heat one pad until the solder flows.
3. Switch to the other pad and heat it until the solder flows.
4. The capacitor should come up off of the board.
5. Place the tip of the iron against the junction of the capacitor’s free connection and the pad under it.

What is SMD Capacitor and How is it Made? SMD Capacitor or Surface Mount Chip Capacitor is an electronic component made up of an insulator between two conductors. This dielectric matter or insulator plays an important role of storing electric charge. There are several types of SMD capacitors.

To hand solder these, add a little solder to one pad on the board. Use a tweezers to hold the component on the board, with one end on top of the solder. Touch the iron to the pin on the pad with the solder. The component should be firmly against the board, and both ends should be lined up with the pads.

Hand soldering is the operation that can be done by hand especially in case of PCB Rework. It is typically performed with a soldering iron, soldering gun, a torch, or occasionally a hot-air pencil.

Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat.

Wave soldering is a bulk soldering process used in the manufacture of printed circuit boards. The circuit board is passed over a pan of molten solder in which a pump produces an upwelling of solder that looks like a standing wave.
