SMT chip processing will use a lot of electronic components, there is a very small volume of SMD material (such as 0201/0402 capacitance resistance, etc.), but also a relatively large volume of components (for example: shielding cover, connectors, BGA, etc.). With the volume of electronic products is getting smaller and smaller, electronic material will also be smaller and smaller, but some electronic products will still use a relatively large electronic components, then the SMD can not be mounted, it is necessary to plug-in. Patch material and plug-in material have their own advantages and disadvantages, the following to introduce the difference between the two.
Advantages of Patch Material
Small volume, patch material is generally very small, many electronic products Z small will use 01005 electronic components, this with the naked eye are almost difficult to see, the smaller the electronic material, the volume of electronic products can be made smaller and smaller.
Low cost:
SMD material suitable for placement machine placement, placement machine has high-speed machine, up to tens of thousands, 100,000 points / hour, can greatly improve the patch production efficiency, improve production capacity, save manpower, time, etc., reduce costs very obvious.
Light weight:
the volume of the patch material is very small, most of them are rolled disc material, can hold a lot.
Strong vibration resistance.
Reduce electromagnetic and radio frequency interference.
Low defective solder joints.
Advantages of Chip Material
1. Power-type electronic parts, high requirements for heat dissipation, plug-in material will be superior to SMD material, because of its larger size, power-type components than the SMD material performance is more stable.
2. Plug-in material failure rate will be lower, and because of the larger volume, more suitable for IQC inspection, more suitable for manual visual inspection without the use of electronic parts inspection equipment, reduce the investment of equipment.
3. Resistance to high frequency, high amplitude vibration and bumps, plug-in material is more stable.
