A method of making a stackable wiring board is characterized by positioning an electronic component in a dielectric recess to realize the thickness reduction of the wiring board and sidewalls of the recess can confine the dislocation of the electronic component to avoid misalignment between buildup circuitry and the electronic component. An array of metal posts that provide vertical electrical connections are formed by using the same metal carrier that forms the recess, so that the predetermined distance and relative location between metal posts and pads / bumps of the electronic component can be maintained.

A film-on-wire spacer covers an entire upper surface of a lower electronic component. Accordingly, an upper electronic component is supported above bond pads and lower bond wires of the lower electronic component. This decreases the stress on the upper electronic component, e.g., during wirebonding, and thus decreases the chance of cracking the upper electronic component. Further, the lower bond wires are enclosed in and protected by the film-on-wire spacer. Further, the film-on-wire spacer is thin resulting in a minimum height of the stacked electronic component package.

The recess in the core provides lateral displacement control between the device and the metal posts, and the minimal height of the metal posts needed for the vertical connection between both opposite sides of the core base can be reduced by the amount equal to the depth of the recess. Further, the semiconductor device is face-to-face electrically coupled to another semiconductor device through a buildup circuitry therebetween.

A teaching aid for instructing proper finger position on a “fret-less” stringed instrument (for example, violin, viola, cello, bass) comprises a template that is positioned along the fingerboard at the proper finger position location (i.e., “first position”) for the first four half-steps associated with each string. A set of raised, “Braille-like” features is formed as a grid pattern on the surface of the template, with each row of features associated with each tone half step. Each “row” contains a set of three raised features—a separate feature located between an adjacent pair of strings. Once the template is properly positioned, the raised features are pressed out of the template and transferred to adhere to the fingerboard. By locating the raised features between the strings, the teaching aid does not interfere with sound quality or the ability to induce vibrato to the playing, while still providing a tactile clue for the proper note location for intonation purposes. Once the student has mastered proper finger placement, the raised features may be removed.
