Digital Logic SimulatorĪ tool used to verity the design (or portions thereof) in the digital domain by applying virtual test signals to a virtual model of the design. DigitizingĪny method of reducing feature locations on a flat plane to digital representation of X-Y co-ordinates. Dimensional HoleĪ hole in a printed board where the means of determining location is by co-ordinate values not necessarily coinciding with the stated grid. Dimensional StabilityĪ measure of dimensional change cause by such factory as temperature, humidity, chemical treatment, age, or stress (usually expressed as units/unit). DIP SolderingĪ process whereby printed boards are brought into contact with the surface of a static pool of molten solder for the purpose of soldering the entire exposed conductive pattern in one operation. Discrete ComponentĪ component which has been fabricated prior to its installation (i.e., resistors, capacitors, diodes, transistors, capacitors, diodes, transistors, etc ). A single function component. DispersentĪ chemical added to the cleaning solution to improve its particulate-removal ability. Disturbed Solder ConnectionĪ solder connection that is characterized by the appearance that there was motion between the metals being joined when the solder was solidifying (not accepted). Information on an assembly that explains the basic design concept, type and quantity of parts and materials, special manufacturing instruction, and up-to-date revisions. Double-sided AssemblyĪ PCB with components mounted on both skies. DPFĪ printed board with a conductive pattern on both sides. The making of soldered terminations by dipping the colder side of a supported printed board with through-hole mounted components into the surface of a static pool of molten solder and moving it horizontal in one direction. Drag-outĪ measure of cleaning solution lost via board emergence after immersion. DRCĭesign Rule Check: Checks the integrity of print (PCB) so that problems like short-circuits, unrouted nets, etc. are recognized. Solid, carbide cutting tools designed specifically for the fast removal of material in extremely abrasive, glass-epoxy materials. Oxide and other contaminates which form on the surface of molten solder. Dry Film ResistsĬoating material in the form of laminated photo-sensitive foils specifically designed for use in the manufacture of printed circuit boards and chemically machined parts. They are resistant to various electroplating and etching processes. Within the re-flow process after pre-heat and before peak re-flow temperature wherein volatile materials escape from the solder paste.

In wave soldering, the first wave’s multi-directional jet leaves solder on all contacted surfaces, followed by the second (flat) wave, which effects a finishing appearance by removing bridges and icicles. Intended for surface mount soldering. Dummy ComponentĪ mechanical package without the die, used to verify placement processes. This review may suggest a prospective guideline for developing high-performance Zn anodes for use in sustainable ZIBs.A measurement of the hardness of a non-metal such as rubber, plastic, etc. Also the instrument for such measurement. In addition, for the purpose of developing a Zn anode that is chemically and electrochemically stable, we thoroughly elucidate the internal mechanisms of the regulation strategies while offering guidance for the rational design of Zn anodes. Herein, we systematically summarize the host-design strategies for the Zn anode regarding substrate (accommodation of Zn deposits) and interface (protection of Zn anode) fabrications. These unavoidable parasitic reactions degrade the output energy/power density and shorten the actual lifespan of the Zn anode, rendering it infeasible for ZIBs to access the practical energy storage system. However, the metal zinc (Zn) that makes ZIBs competitive is now being plagued by dendrite growth and spontaneous side reactions (hydrogen evolution reaction and water-induced corrosion).

Aqueous zinc-ion batteries (ZIBs) distinguish themselves among the numerous viable alternatives to lithium-ion batteries on account of their potential advantages, which encompass enhanced safety, cost-effectiveness, and eco-friendliness.
