turnkey process details

What tasks are required to complete my product development, and what will you deliver to me?

A typical electronic product development can be broken down into the following broad categories:

Electronic/PCB Design
Software/FPGA Design
Enclosure Selection/Design
Manufacturing

When we provide a quote to you, each task which applies to your development will be listed with an estimate of hours required for completion. The costs for PCB manufacture, components, and assembly will also be included. Dallas Logic can provide production volume for your finished product. A general summary of design tasks are listed in the tables below.

Electronic Design Tasks

Design Task	Deliverable	Notes
1) Product specification and requirements.	Sample_spec.doc	Supplied by customer or created as part of the development. See the Request Quote page for details of what this document should contain.
2) Detailed physical circuit design.	Sample_block_diag.ppt	Block diagram of all circuits and parts selected. Adds detail to any existing specification diagrams as submitted by customer.
3) CAD parts library coding	Sample.lbr	CAD part coding of non-standard and special components.
4) Order components	Parts kit	Long lead components start after library coding. Will finish up at end of PCB layout. Also order programming cables or special lab supplies.
5) Schematic capture.	Sample.sch	Circuit design is finished at completion of this task.
6) Design of physical PCB.		Define overall design rules (trace width and clearances) Power planes, copper requirements, mechanical design, routing, cutouts, tooling holes, component clearance.Test-points, Layer stackup, Controlled impedance, Special trace requirements (differential spacing, ground plane proximity). Special PCB shape to fit off-the-shelf enclosure or custom enclosure?
7) PCB layout	Sample.brd	Implement PCB outline and tooling holes, place components, manual route critical signals and power, auto route bus and local groups, auto route remainder, clean traces, clean silkscreen.
8) Layout verification		Run DRC and verify all errors, manual check of PCB footprints against components or data sheets, manual check of critical nets.
9) Gerber and fabrication drawing preparation and checking.	Sample_gerb.zip Sample_stackup.txt Sample_fab_top.pdf Sample_fab_bot.pdf	Gerber files for board build. Read-me file defining layer stackup. Fabrication drawing to include auto dimensioning of board, with .pdf creation of top-side views. Diagram of required layer stack-up and definition of controlled impedance requirements. Definition of any other special mechanical requirements (routing, cutouts, etc).
10) Select PCB fabrication vendor and transfer build files.		Include electrical test of bare board.
11) Initial component assembly	Assembled PCB	Prototype for design verification.
12) Design Verification	Working PCB	Debug of design in lab. May require compliance testing (over temp/voltage).
13) Schematic cleanup	Sample.sch New revision	New revision of the schematic.
14) Layout clean up	Sample.brd New revision	New revision of the PCB layout.

Manufacturing Tasks

1) Manufacturing test design	Test software/files. Test fixtures	Generate functional test procedures and required testing code. Will utilize working prototype board and test fixture to provide tests. Emphasis also place on self diagnostics built into the design. Provide ICT (in circuit test) and fabricate test fixturing for larger production runs.
2) Packaging diagram and user documentation	Sample_user_manual.doc Sample_pack_diag.ppt	Will make use of specification document and circuit block diagrams, as well as manufacturers data sheets for components. Include example source code listings. Packaging diagram and specifications for manufacturer (packaging for shipment or display to end user).
3) Manufacturing parts kit and ship	Manufacturing parts kit	"Jelly-bean" parts generally supplied by manufacturer. Integrated circuits ordered and shipped to manufacturer. Can provide domestic or overseas assembly.
4) Manufacturer support per build.		Have manufacturer pre-build one board for testing prior to large production run (more than 10 units).
5) Receive and test/inspect each board prior to customer delivery (one to hundreds of units)	Working boards for customer	Functional test may have already been run at manufacturers site (depending on production quantity). Full functional testing must be specified.
6) Warrantee and return policy.		Who and how will returns be repaired?

Enclosure Design Tasks (as applicable to the PCB design)

1) Select off-the-shelf unit or specify design of custom enclosure.	Manufacturers part number or mechanical drawings for custom enclosure	This data will specify the shape and location of tooling holes on PCB. Generally plastic, aluminum, steel, fiberglass materials.
2) Sub-system fit.		Preliminary analysis of the sub-systems mechanical assembly. Might include batteries, cabling, displays, panel buttons, antennas, cover-plates, etc.
3) Cosmetics.		Any special requirements as far as color (painting), transparency, lighting.
4) Indicators.		Selection, fit and feel of buttons, switches, displays, etc. for user operation.
5) Environmental analysis		Ability of mechanical design to keep electronics within required operating range with respect to shock, temperature and vibration
6) Compliance		FCC, EMI, UL
