Abstract
A compact printed circuit board assembly includes a printed circuit board (PCB) and a preamplifier subassembly. The preamplifier subassembly includes a preamplifier and an insulating endcap abutting one another and arranged in a plane parallel to the PCB. An electrical via formed within the first insulating endcap provides an electrical connection between a decoupling capacitor and the PCB to reduce noise detectable in current flowing between the preamplifier and a current source.
Claims20
A printed circuit board assembly comprising:
- a printed circuit board (PCB);
- a preamplifier subassembly electrically coupled to the PCB and further coupled to a read or write head, the preamplifier subassembly including:
- a preamplifier with a first surface abutting a first insulating endcap, the preamplifier and the first insulating endcap arranged in a first plane parallel to a primary plane of the PCB;
- and
- an electrical via formed within the first insulating endcap and providing an electrical connection between a first decoupling capacitor and at least one of the PCB and the preamplifier to reduce noise detectable in current flowing between the preamplifier and a current source.
(canceled)
A method comprising:
- attaching a printed circuit board (PCB) to a preamplifier subassembly including a preamplifier abutting a first insulating endcap, the first insulating endcap including an electrical via providing an electrical connection between a first decoupling capacitor and at least one of the PCB and the preamplifier to reduce noise detectable in current flowing between the preamplifier and a current source, the preamplifier and the first insulating endcap arranged in a first plane parallel to a primary plane of the PCB, the preamplifier providing current to a read or write head.
(canceled)
A printed circuit board assembly comprising:
- a printed circuit board (PCB);
- a preamplifier subassembly electrically coupled to the PCB and including at least a first preamplifier and a second preamplifier arranged in a second plane parallel to a primary plane of the PCB, the first preamplifier and the second preamplifier separated from one another by a first insulating endcap including an electrical via that provides an electrical connection between a decoupling capacitor and at least one of the PCB and the preamplifier subassembly to reduce noise detectable in current flowing between a current source and at least one of the first preamplifier or the second preamplifier.
