[0020] While embodiments of the invention are susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION
[0021] Referring generally to
[0022] Generally, the component 110 is a component for use in an electronic device, such as, for example, a printed circuit board (PCB), a micro-interconnect, a microcircuit, a hard disk drive suspension component, a hard disk drive flexure, a sensor, a medical device component, an actuator, a light emitting diode (LED), a processor, micro-electromechanical system (MEMS), or the like. The component 110 includes a substrate 112. The substrate 112 can be made from, for example, a metal (e.g., stainless steel), a polymer (e.g., polyimide), ceramic, or any combination thereof. As shown in
[0023] The carrier strip 120 has an upper surface 120A and a lower surface 120B (
[0024] As best shown in
[0025] The polymeric tab 130 is used to couple the component 110 to the carrier strip 120 and includes a first portion 132 and a second portion 134. As shown, the first portion 132 is coupled to the upper surface 120A (
[0026] As shown, the second portion 134 of the polymeric tab 130 extends a first distance from the edge 114 of the substrate 112 onto the upper surface 112A (
[0027] While the first portion 132 of the polymeric tab 130 is shown as being coupled to the upper surface 112A of the substrate 112 and the second portion 134 is shown as being coupled to the upper surface 112A (
[0028] Referring to
[0029] The optional metal tab 140 can be used to support the component 110 during one or more etching processes during manufacture of the component 110 in the panel 100. This is advantageous because the polymeric strip 130 may not possess sufficient structural strength to keep the component 110 coupled to the carrier strip 120 during the etching processes without failing (e.g., delaminating and/or fracturing). The optional metal tab 140 can be separated from the component 110 as part of the etching process, or after completion of the etching processes, by using a laser, or by shearing and/or bending the carrier strip 120 in a forming die, for example. In contrast, according to some embodiments, the polymeric tab 130 remains in the panel 100 until all of the processing steps required to produce the finished component 110, and then the polymeric tab 130 is removed using the method described in detail below, for example.
[0030] While the panel 100 in
[0031] A method for detaching the component 110 from the carrier strip 120 by separating the polymeric tab 130 from the substrate 112 of the component 110 is described in reference to
[0032] The first spring clamp 310 of the tab removal device 300 is positioned directly adjacent to the lower surface 112B of the substrate 112 of the component 110 and secures the component 110 to the tab removal device 300. Similarly, the second spring clamp 320 of the tab removal device 300 is positioned directly adjacent to the lower surface 120B of the carrier strip 120 and secures the carrier strip 120 to the tab removal device 300. As shown in
[0033] Referring to
[0034] As linear movement of the ejector pin 340 continues to cause linear movement of the component 110 in the direction of arrow A, the peeling force applied to the polymeric tab 130 increases until the peeling force is sufficient to cause the second portion 134 of the polymeric tab 130 to separate from (e.g., delaminate from) the upper surface 112A of the substrate 112 of the component 110. The required peeling force corresponds to the distance between the edge 124 of the carrier strip 120 and the edge 114 of the substrate 112 of the component 110. More specifically, a greater distance between edge 124 of the carrier strip 120 from an edge 114 of the substrate 112 of the component 110 requires a greater peeling force. For example, reducing the distance from about 200 microns to about 100 microns reduces the required peeling force.
[0035] Advantageously, the force that the tab removal device 300 is required to impart in order to separate (e.g., delaminate) the polymeric tab 130 from the upper surface 120A of the substrate 120 is less than the force required to separate (e.g., fracture) the optional metal tab 140 from the component 110. For example, the force that the tab removal device 300 is required to impart can be 75% of the force required to separate (e.g., fracture) the optional metal tab 140 from the component 110, 60% of the force required to separate (e.g., fracture) the optional metal tab 140 from the component 110, 45% of the force required to separate (e.g., fracture) the optional metal tab 140 from the component 110, 30% of the force required to separate (e.g., fracture) the optional metal tab 140 from the component 110, 15% of the force required to separate (e.g., fracture) the optional metal tab 140 from the component 110, etc. A reduction in the force required to separate (e.g., delaminate) the polymeric tab 130 from the upper surface 120A of the substrate 112 of the component 110 can also permit an increase in the density (e.g., number) of components in the panel 100.
[0036] According to some embodiments, the separating of the second portion 134 from the substrate 112 of the component 110 (e.g., using the method described above in reference to
[0037] According to some embodiments, the upper surface 112A (

[0041] Referring to
[0042] Advantageously, the polymeric tab 630 is stronger than the polymeric tab 130 described above because the polymeric tab 630 completely surrounds the outer edge of the component 610. Further, applying a peel force (e.g., using the same or similar method as described above in reference to
[0043] Referring to
[0044] An adhesive force between the polymeric tab and the adhesive sheet is greater than an adhesive force between the substrate of the component and the adhesive sheet. The difference in adhesive force aids in separating the polymeric tab from the component during the second step 720, where the adhesive sheet is peeled from the substrate of the component. Alternatively, rather than continuing from the first step 710 to the second step 720, the method 700 can include continuing from the first step 710 to the second step 720, which includes linearly moving, using an ejector pin that is the same as or similar to embodiments of the ejector pin (see e.g.,
[0045] While embodiments of the present invention have been described with reference to one or more particular embodiments, those skilled in the art will recognize that many changes may be made thereto without departing from the spirit and scope of the present invention. Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of embodiments of the invention described herein. It is also contemplated that additional embodiments may combine any number of features from any of the embodiments described herein.
