How to specify a PCB?
A PCB user generally needs to present all of the primary manufacturing data in a complete and unambiguous way that the PCB manufacturer can quote and produce the boards without error.
A checklist is listed as follows. Some parameters not necessary for a particular job can be deleted so that the specification form only reflects the relevant data.
(1) Company name
(2) Part number
(3) Lot size and annual requirements
(4) Layer count
(5) Board size
(6) Board thickness
(7) Board shape
(8) Panelization
(9) Board build-up
(10) Boards with controlled impedance
(11) Test coupon
(12) Machining (Contouring)
(13) Laminate type and UL flammability
(14) Warp & Twist
(15) Outer layers
(16) Inner layers
(17) Solderability preservation
(18) Solder masks
(19) Notation
(20) Peelable solder mask
(21) Carbon printing
(22) Plated through holes (PTHs)
(23) Non-PTHs
(24) Milled Holes (Slots)
(25) Blind via holes
(26) Buried via holes
(27) Board tooling holes
(28) Panel tooling holes
(29) Board mounting
(30) Edge connectors
(31) Soldering conditions
(32) Markings
(33) Electrical test
(34) Automatic optical inspection
(35) Minimum pattern conditions
(36) Quality conditions
