SMT DIP Manufacturer & Assembly – One-stop service

Kingford currently has three SMT DIP lines, all of which use the YAMAHA brand. YSM20R is our newly introduced machine. The theoretical production capacity is 96000CPH. And the high-speed universal integrated head is the fastest universal placement machine in the world.

This model can play 140 kinds of materials, 70 stations in front and rear, support belt type, disc type, rod type tray. It can mount 0201 components, mounting accuracy reaches ±0.025mm. It can meet the high of different types of products Precision placement requirements.

With reflow soldering in the ten-temperature zone, the solder paste and components are fully integrated. To reduce the occurrence of false soldering and soldering problems. 100% of all products that have been placed are tested by AOI to eliminate placement errors and placement defects.  Thereby to improve the yield rate and ensure product quality.

Advantages of SMT Dip chip processing:

  • High assembly density, small size, and lightweight of electronic products.
  • High reliability and strong seismic resistance. The solder joint defect rate is low.
  • High-frequency characteristics are good. Reduced electromagnetic and radio frequency interference.
  • Easy to automate and increase productivity. Reduce costs by 30% to 50%. Save materials, energy, equipment, manpower, time, etc.

Through Hole assembly:

В настоящее время Kingford использует паяльную машину для бессвинцовой пайки. Принцип пайки волной припоя заключается в достижении одноразового быстрого процесса пайки путем раскатывания расплавленной паяльной пасты до образования пика. И припаиваем контакт к печатной платы со вставленными компонентами. По сравнению с ручной сваркой он имеет высокий КПД и хороший сварочный эффект и подходит для массового производства. Появление двойных выступов решает большинство проблем, таких как плохое лужение, улучшает выход продукции, сокращает объем ручного ремонта и обеспечивает качество сварки.

The principle is that the first peak acts by a rapid movement to wash the flux trapped in the plug’s foot, and the untinted part is lubricated. After the second peak, the irregular part of the tin is corrected again, and the tin is not applied. It is also supplemented to make it more rounded and the welding effect is better. At the same time, we are equipped with the later AOI inspection to better solve the welding defects such as misplaced parts, missing welding, bridging and not being welded, which improves the welding reliability.

Double-wave soldering Because SMD does not have a mounting jack like THD, the gas volatilized by the flux is nowhere to be emitted. In addition, SMD has a certain height and width and is high-density mounting, and the solder surface has tension.

Therefore, it is difficult for the solder to penetrate into every corner of the mounting component in time, so if a single wave soldering is used, a large amount of leakage welding and bridging will occur, and double wave soldering must be used to solve the above problem. Double wave soldering: There are two peaks before and after the tin furnace. The former one is narrower (the ratio of wave height to wave width is greater than 1).

The peak-end has 2-3 sweep b staggered small peaks, which are constantly flowing up and down in such a long position. Under the action of turbulent waves, the gas generated by the flux is removed, and the surface tension is also weakened, so that good welding is obtained. The latter peak is a wide-width wave in both directions, and the solder flow is flat and slow, which can remove excess solder and eliminate undesirable phenomena such as burrs and bridges.
