Through-hole technology almost completely replaced earlier electronics assembly techniques such as point-to-point construction. From the second generation of computers in the 1950s until surface-mount technology (SMT) became popular in the late 1980s, every component on a typical PCB was a through-hole component.
This makes boards with through-hole mounting technology very durable, which is partly why they are used in military and aerospace. They also have a high temperature tolerance. You can find through-hole technology in all sorts of places. One example is on LED lights in billboards or stadiums.
3-4-2017· Our PCB through-hole technology capabilities include auto insertion, wave soldering, and selective soldering. With the lowest employee turnover in our industry, you can count on the person who builds your PCB to be familiar with
Through-Hole Mounting (THM): Through-hole mounting is the process by which component leads are placed into drilled holes on a bare PCB. The process was standard practice until the rise of surface mount technology (SMT) in the 1980s, at which time it was expected to completely phase out through-hole.

In some cases there is no alternative for a through hole component. When the size is too large, when mechanical stress is too high or when power dissipation is too much. With some components the SMD type can be bought only in reels of at least 1,000 pieces, while all you need is 100 pieces. In those situations through hole components are selected.
Through-hole PCB Assembly Manufacturing Process Whilst conventional manual through-hole soldering has a part to play at prototype and for very small volume, in concert with the efficiency of surface mount technology (SMT), Cogent seeks to apply the most efficient methodology available.
Our UK robotic production facilities can automatically place and crop the spills of through-hole components before automated soldering. Our PCB Manufacturing
Qualitel uses manual soldering, selective soldering, and wave soldering processes to ensure that your through-hole components are assembled with the highest reliability and repeatability in mind. Get in touch today let’s talk about how Qualitel’s manufacturing can help you focus on what you do best.
A hole is an opening, usually circular, in or through a particular medium, usually a solid body. Holes occur through natural and artificial processes, and may be useful for various purposes, or may represent a problem needing to be addressed in many fields of engineering.
Through-hole / Mixed State-of-the-art Contract Manufacturing . In order to decrease manufacturing time and costs, TL Industries has invested in a number of through-hole manufacturing equipment systems. This equipment includes axial lead insertion equipment, DIP IC Inserter and operator assisted through-hole insertion equipment.
Our through-hole PCB assembly procedure can handle both leaded & lead-free applications. Precise component interconnections and exact soldering temperatures provide superior solder joint integrity. Our circuits are inspected throughout the PCB assembly process to ensure a high-quality final product.
Leaded, soldered components have been the traditional answer in the electronics industry for decades. Despite the movement toward the use of surface mount technology to handle the increased complexity of modern circuit boards, through hole assembly still has a significant role to play. Even on a

A plated through-hole is a hole in the PCB that's plated all the way through the board. PCB components use these holes to pass a signal from one side of the board to the other. In this case, soldering paste won't do any good, as the paste will run straight through the hole without a
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 PCBs and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines.

Through-hole components require a lot of space on a PCB in comparison to surface mounted components. Most through-hole mounted components need to be placed manually. Surface Mounting (SMT) Surface Mount technology was introduced around 1960 and became widely used in the mid-80s.
29-3-2017· Plating Through Hole(PTH) Plating through hole is the most common via, just take up PCB and face to the light, if you can see the light, then it is the “through hole”. PTH is also the simplest kind of hole because it just need to use drill or laser light to make a full borehole, and the cost is relatively cheap.
Our through-hole assembly capabilities include three axial insertion machines, two DIP insertion machines and six wave solder lines for quicker and higher quality production.
Through-Hole Component Assembly (THT) Traditional leaded through-hole components can be either flow soldered or fitted by our dedicated, highly skilled assembly team. This approach offers a robust, high precision expedient assembly solution.

Although through-hole assembly is an established and proven process, it is still one of the most robust and widely used construction technologies used in product manufacture.
Through hole technology and its use in multi-layer PCBs was patented by the U.S. firm Hazeltyne in 1961. The The miniaturization of electronic products continues to drive printed circuit board manufacturing towards smaller and more densely packed boards with increased electronic capabilities.
