Abstract

A method a described which includes depositing a first component of a multicomponent system by means of an inkjet process, and depositing a second component of the multicomponent system by means of an inkjet process.

First claim

What is claimed is:

1. A method, comprising:
depositing a first component of a multicomponent system on an electronic component by means of an inkjet process; and
depositing a second component of the multicomponent system on an electronic component by means of an inkjet process,
wherein the first component comprises a resin, the second component comprises a curing agent, and the multicomponent system comprises an epoxy resin,
wherein the first component and the second component are deposited in each case in droplet form, and spacings between the deposited droplets are such that the droplets do not mix as a result of spreading of the droplets; wherein the first and second components have contacting surfaces.

2. The method of claim 1 , wherein the first component is deposited with a first print head of a dual print head and the second component is deposited with a second print head of the dual print head.

3. The method of claim 1 , wherein the first component and the second component are deposited at the same time.

4. The method of claim 1 , wherein the first component and the second component are deposited onto an identical area.

5. The method of claim 1 , wherein the first component and the second component are separated spatially from one another after being deposited.

6. The method of claim 1 , wherein the first component is deposited onto a first area, the second component is deposited onto a second area, and the first area and the second area brought into contact, the first component and the second component.

7. The method of claim 1 , wherein at least one of the first component and the second component is deposited in droplet form, and the diameter of the deposited droplets are in a range from 1 micrometer to 1000 micrometers.

8. The method of claim 1 , wherein at least one of the first component and the second component is deposited in the form of droplets with a diameter, and a maximum spacing between the deposited droplets is in a range from 1% of the diameter to 50% of the diameter.

9. The method of claim 1 , further comprising:
curing a mixture of the first component and second component at a temperature in a range from −20° C. to 300° C.

10. The method of claim 1 , further comprising:
coating or encapsulating semiconductor component with the multicomponent system.

11. The method of claim 1 , further comprising:
coating the electronic component having a semiconductor wafer with the multicomponent system.

12. The method of claim 1 , further comprising:
adhesively bonding two objects together by way of the multicomponent system.

13. The method of claim 1 , further comprising:
chemically reacting the first component with the second component to produce the multicomponent system.

14. The method of claim 1 , wherein the multicomponent system comprises a multicomponent adhesive.

15. A method, comprising:
depositing a first component of a multicomponent system on an electronic component by means of an inkjet process; and
depositing a second component of the multicomponent system on an electronic component by means of an inkjet process,
wherein the first component and the second component are deposited in each case in droplet form, and spacings between the deposited droplets are such that the droplets do not mix as a result of spreading of the droplets; wherein the first and second components have contacting surfaces.
