  • Publication number: 20220382961
    Abstract: Methods, systems, apparatuses, and computer-readable storage mediums are described for rendering document changes. A first document is rendered in a client user interface (UI) based at least on a first intermediate format representation obtained from a server. A change initiator receives a request for a change to the first document and transmits information indicative of the change to the server. A client renderer selectively modifies a portion of the first intermediate format representation at the client based on the change and renders a modified first document in the UI based at least on the modified first intermediate format representation. The client renderer obtains a second intermediate format representation from the server, where the second intermediate format representation comprises an intermediate format representation generated through processing an updated document definition. The client renderer renders the second document in the UI based at least on the second intermediate format representation.

  • Patent number: 11476174
    Abstract: Embodiments described herein provide techniques for forming a solder mask having a repeating pattern of features formed therein. The repeating pattern of features can be conceptually understood as a plurality of groove structures formed in the solder mask. The solder mask can be included in a semiconductor package that comprises the solder mask over a substrate and a molding compound over the solder mask that conforms to the repeating pattern of features. Several advantages are attributable to embodiments of the solder mask described herein. One advantage is that the repeating pattern of features formed in the solder mask increase the contact area between the solder mask and the molding compound. Increasing the contact area can assist with increasing adherence and conformance of the molding compound to the solder mask. This increased adherence and conformance assists with minimizing or eliminating interfacial delamination.
