SMT SNAP IN LOCK claw buckle gradually replace traditional screws. PCBs are buckled with vertical through-hole claws to improve assembly time efficiency. SMT surface mount technology ensures the most stable assembly between components and PCBs.


For example, when the traditional pointed locking pin SMT PIN is inserted into the PCB, it will often face product quality instability due to various reasons, such as skew, deviation, loose parts or excessive position, and when fixed and assembled on the PCB, all these Poor quality will cause damage to the PCB or cause more serious cracks or high defect rates such as NG parts, resulting in waste of time and cost. If you change to adopt SMT SNAP IN LOCK claw buckle, when the claw buckle is vertically inserted into the through hole for claw buckle connection, the special claw buckle head design can be used to buckle by the extension force of the claw metal to extend outward The through-hole grooves on both sides can reversely buckle the PCB card, and can be fixed vertically to repeat the claw buckle placement operation process, gradually replacing the traditional screw lock or PIN lock, improving time and cost efficiency. Compared with traditional screws, it saves 90% of assembly time.


SMT surface mount technology, first insert the claw button to the SMT reel, and then carry out the automatic suction and placement process, suck the claw button of the vacuum nozzle from the reel, and then transfer it onto the PCB, and then pass the SMT uses solder paste technology for soldering. The process is carried out in four steps through heating-immersion-reflow cooling, cooling and solidification into a solid metal template to complete the soldering process and complete the installation. This technology is to cool the liquid solder paste into a solid metal form. The whole process uses SMT automated machines, which will not cause the parts to be loose and skewed, and it can reach a 100% pass rate. The use of SMT fixed claw button technology on PCB is gradually replacing traditional PCB assembly technology.

Type of mounting style on PCB application

In addition, in the SMT process, due to the different materials and shapes of the metal parts, in order to more effectively achieve the suction effect of the vacuum tip, it is recommended to use Connect-cap to cover the top groove to maximize the stability of the vacuum, so as to Easily pick up and place in the holes on the PCB. After installation, remove the connection cover.





SMT SNAP IN LOCK表面贴装技术爪扣逐渐取代传统螺丝,PCB以垂直下插通孔爪扣进行扣接可提高组装时间效率,SMT表面贴装技术确保组件和PCB之间最稳定的组装



如使用传统的尖头锁定销SMT PIN插入PCB上时,往往会因各种原因操作而面临产品品质不稳定性,例如歪斜,偏差,零件松动或位置过大,而在PCB上固定组装时,所有这些品质不良性将导致PCB损坏或造成更严重的裂缝或NG零件等高不良率而导致时间成本之浪费。如改采用SMT SNAP IN LOCK表面贴装技术爪扣,爪扣垂直向下插入通孔进行爪扣扣接时,可利用特殊爪扣头型设计, 利用爪扣金属向外侧沿伸扩展力扣住两侧通孔凹槽,可反向扣住PCB板卡,可垂直固定重复进行爪扣扣接放置操作过程, 逐渐取代传统螺丝锁或PIN插销,提高时间成本效益。与传统螺丝相比,节省90%的组装时间。
















Fivetech SMT Solder Stop 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 Solder Stop 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 Solder Stop Nut welding technology to bring benefits to our customers.

Fivetech 82 series SMT NUT 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 uts 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 fully automatic SMT welding assembly, quick disassembly and assembly without using general screws, high-strength soldering welding combined force, low profile, micro miniaturization, suitable for mobile phones / notebooks / server / Networking/Telecom / Industrial Computer / Cloud / TV / Monitor ...

Save 90% assembly time compared with traditional screws

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.
