Fivetech SMT stop ring nut prevent the backflow of solder paste during SMT assembly to prevent thread contamination or damage.


Although the SMT process refers to the technology of melting tin as glue to the stable mechanical parts on the panel, the excess liquid tin can easily flow back to the inside of the bracket / nut, causing serious damage and pollution. The inflowing tin can damage the thread of the part. It forms tin shavings, uneven thread spirals, tin bumps and other defects. Due to the forced tightening, it is impossible to screw in and the solder spatters. Solder splatter not only damages the parts, but also causes tin chips to splash onto the PCB board, resulting in greater mechanical problems. The possibility of short circuit is also very high. This defect severely increases the failure rate of the product and increases the cost of rework. To make matters worse, due to rework, the production time will be extended.


Fivetech SMT stop ring nut welding technology is the best way to solve this problem. The solder resist requires a stop ring plug that is mechanically placed at the bottom of the nut / support. It seamlessly matches the thread size. When SMT is used to mechanically seal these parts to the panel, the stop ring stop ring prevents liquid tin from flowing into the threaded hole. Therefore, it can keep the thread intact. It can then be easily removed by tool punching without leaving any marks or damage. The stop ring plug has high welding reliability, which can prevent the internal structure and threads of the ferrule from being damaged due to the inflow of the tines, which may result in the reduction of the float volume or the flow of solder paste between the PCB and the external ferrule. This may cause unstable reliability or other problems.


With the application of solder resist, defective nuts / supports have been significantly reduced. Ultimately, it can optimize the success rate of the production line. It can save costs, save time and increase the success rate. We strongly recommend Fivetech SMT stop ring nut welding technology to bring benefits to our customers.


Fivetech SMT Nut 82 series can provide a complete product line for all thread sizes. The SMT welding process can eliminate the cause of stamping damage, thereby avoiding the risk of PCB damage. Fivetech 82 series SMT nuts used on PCBs have been widely accepted by the market. SMT technology has gradually developed into a mature technology, gradually replacing traditional assembly through its SMT process, so that the assembly process can achieve maximum yield, the industry can use the existing SMT production line, use vacuum nozzles to pick up SMT nuts On the reel, pick and place it on the tin solder pasted on the PCB. Through the tin heating and cooling process, the tin is melted and cooled to a solid state to complete the SMT nut assembly process. The SMT process can reduce the damage to the PCB caused by the placement of nuts on the PCB due to the deflection of the punch. This result is usually easy to damage the circuit board. In order to improve, the SMT process can accurately locate and obtain the maximum output.

Fivetech SMT SPOOL are specially designed to assemble the sub-card quickly and easily to the server motherboard, quickly reconnect or disassemble, and the sub card can be locked in seconds. Just slide the sub card through the gourd-shaped hole to quickly connect or remove , and slide left and right to the horizontal locking direction.

Due to the application requirements of the server motherboard, various types of sub cards are usually required. The installation of most sub cards requires traditional screws that cannot be quickly removed and replaced. SMT SPOOL can be bent at different heights and can be between boards and boards Used as a high plate gasket. Low profile and micro miniaturization; SMT surface mount technology refers to the surface mounting technology that melts tin into tin glue until it cools and stabilizes the SMT studs on the PCB panel. SMT spool provide different functions and installation designs; micro miniature low profile can be used for mobile phones / notebooks / server / Networking/Telecom /industrial computers / clouds / TV / monitors ..... SMT engineering the high-profile shims can be used as four-post shims on slot servers; customers often use SMT spool+ fixing screws on server boards, which can emphasize the convenience of card installation and the characteristics of easy replacement.

When the safe assembly method is so complicated, SMT spool are really flexible when engineers move the chassis and replace cards. The design body has the purpose of easy assembly and quick release. Since threaded connections are disabled, simply place the sub board down through the larger hole of the hoist hole, and then slide the second board to the horizontal locking direction to insert the panel into the smaller hole. It is fixed in the second position as tightly as other fasteners. It expands the range of product applications. You can also press it into the side of the chassis or panel to fix the panel or panel on the side of the chassis. It not only saves ground space, but also makes full use of three-dimensional space. SMT spool are used in chassis with limited space on motherboards that cannot be driven vertically. The horizontal locking system saves execution space. It saves operation time and provides the simplest fastening method.

New Fivetech SMT Spool special designed for quick remove and easy replace sub-cards to the server mainboard, fast re-connect or dismantle to complete the card-locking in just a second by simply place the sub-card downwards through the gourd-shape hole, then slide right-leftwards to horizontal locking direction.      

Due to the server application requirements of the server main board, it is often necessary to install various types of sub-cards onto the server motherboard, most of the sub-cards installation cannot be quickly removed or replaced, the dismantle function cannot reach second-buckle replacement. New Fivetech SMT Spool emphasizes that the motherboard can be connected with different sub-cards by spool-in installation in just a second. SMT Spool can be buckled at different heights, can be used between board to board as the high plate spacer. SMT process refers to surface mount technique of heat melting tin to tin-glue till cooling stables the SMT spool onto the PCB faceplates.

SMT Spool offers different functional and installation designs; SMT Spool micro low-profile can be using in mobile phones or notebook products; SMT Spool high-profile spacer can be used at the slot server as four-post spacer; SMT spring spool can be divided into non-locking version/locking version to define the different requirements for the lock card. Customers commonly uses on the server board combines SMT Spool + SMT Captive Screw, can emphasize the convenience of card installation and easy replacement.

SMT Spool thus contributing greatly to its product fastening purposes. Spool also adds a stopper piece in between main board and sub-boards. Using the spool sec-installation as the stopper piece, SMT Spool tightly sec-secures any panels in between caps and as the stopper piece. For another advantage, with the SMT spool fastening, it leaves level of method options between all fastened panels. When secured assembly methods are so complex, spool does make flexibilities when engineers move chassis and replace cards. Spool design main presents easy assembly and quick release purposes. As thread screwing is sort of disabled, by simply place the sub-board downwards through the bigger hole of the gourd hole, then slide the sub-board right-leftwards to horizontal locking direction the panel into the smaller hole. It second-secures as tightly as any other fasteners. It widens the product application spheres. It can additionally be pressed-in to the sides of chassis or faceplates, thus secures panels or faceplates on the sides of chassis as well. Not only does it save up ground space, it makes the best usage of a three-dimensional space.

Spool comes in useful for space limited chassis of main board where vertical actuation cannot be operated. For better, Spool’s horizontal locking system saves actuation space. Spool saves space, saves operation time and provides the easiest fastening method. SMT Spool can also be used as side-hangers, saving ground space.
