Package structure
View Patent ↗A package structure including a device, an interconnecting element, a pad and a protecting element is provided. The device connects with a first end of the interconnecting element through the pad. The protecting element covers the pad and the first end of the interconnecting element.
1. A package structure, comprising:
a device;
a plurality of pads connecting with said device;
at least an interconnecting element including a first end and a second end, the first and second ends being coplanar wherein said first end directly connects with said pad;
a first isolating layer formed between said device and said interconnecting element;
a connecting element connecting with said second end of said interconnecting element;
a protecting element covering said plurality of pads and said first end of said interconnecting element to absorb strains formed on a solder joint between said plurality of pads and said interconnecting element generated by temperature changes or impacts by deformations of leads of said solder joint to prevent said solder joint from breaking, wherein said second end of said interconnecting element is not covered by said protecting element; and
a second isolating layer formed on said interconnecting element and said device and wherein the first isolating layer and the protecting element not being extended laterally beyond a periphery of the device.
2. The package structure according to claim 1 , wherein said device is an active device.
3. The package structure according to claim 1 , wherein said device is a passive device.
4. The package structure according to claim 1 , wherein said protecting element is made of plastic.
5. The package structure according to claim 1 , wherein said protecting element is made of ceramic.
6. The package structure according to claim 1 , wherein said protecting element is made of rubber.
7. The package structure according to claim 1 , further comprising a substrate sticking on said device.
8. The package structure according to claim 7 , wherein said substrate is made of rigid material.
9. The package structure according to claim 7 , wherein said substrate is made of flexible material.
10. The package structure according to claim 1 , wherein said second protecting element is thicker than said isolating layer formed on said interconnecting element and said device, and thus said protecting element is exposed outside said second isolating layer.
11. The package structure according to claim 1 , wherein said protecting element is thinner than said second isolating layer formed on said interconnecting element and said device, and thus said protecting element is covered by said second isolating layer.
12. The package structure according to claim 1 , wherein said connecting element is a solder ball.
13. The package structure according to claim 1 , wherein said connecting element is a pin.
14. The package structure according to claim 1 , wherein said connecting element is a solder pad.
