Members Tutorial: Acquisition Process Overview. Each acquisition program falls into an Acquisition Category (ACAT) depending on its overall funding level and importance. The category dictates the level of oversight a program will require. This oversight is provided by a Milestone Decision Authority (MDA) which is appointed by DoD senior leadership.
This section is short and basically describes the design process and considerations. The discussion is based on a circuit design flowchart (see Figure 1). As can be seen from the flow chart, the first task is to determine how the board will be used (Design Inputs) and the resources available to manufacture the board (Administrative Inputs).
Dec 01, 2015· PCB Fabrication Process by Sierra Assembly. The paper on which the layout is printed must be removed at this stage. The easiest and fastest way to accomplish this is soaking the substrate in water for some time. Wait for a few minutes and take the substrate out from the water. Peel off the paper from the assembly.
Thick film pastes (inks) form insulators, overglazes, conductors, capacitors, resistors, crossover connections, and multilayerinterconnect structure. Figure 1 Flow Chart for thick film printing Solid, or plated, through holes or wraparounds connect the top and bottom surface to high frequency ground planes, interconnect or for thermal management requirements.

May 17, 2016· This means that the circuit board design will be checked out and verified along the way called "signout" before it can take the final step to the tapeout process. By the time tapeout is reached, there is usually a collective sigh of relief as all the stages .
The number of applications of integrated circuits in highperformance computing, telecommunications, and consumer electronics has been rising steadily, and at a very fast pace. Typically, the required computational power (or, in other words, the intelligence) of these applications is the driving force for the fast development of this field.
