TIP #029: Be sure you connect enough pins on connector
Why? Connector pins only can carry limited current.
TIP #028: When you are looking for a component, you may ...
Why? It compares components between more manufacturers and shows a lot of important information.
TIP #027: Use at least 2 monitors
Why? It’s much more comfortable during HW design. You can open Schematic in one monitor and PCB in the second.
TIP #026: Do not place memory chips too close to CPU
Why? It may be difficult to route the interface and do length matching. You may need space between the memory chips and between CPU & Memory chip.
TIP #025: Try to use big gap / clearance between signals
Why? Big gap / clearance between tracks lower influence between them (e.g. crosstalk)
TIP #024: Place Reference point of a footprint for ...
Why? This reference point is very often used in Pick & Place output files. When doing assembling, machine will pick up the component at this 0,0 position.
TIP #023: Don’t be scared of creating components
Why? You need to know how to do it
TIP #022: Place ESD protection close to the connectors
Why? So the ESD pulse doesn’t travel through your board and it discharges immediately behind the connector
TIP #021: If possible, have two soldering irons
Why? It’s very useful for desoldering components like resistors, capacitors and even some chips
TIP #020: Don’t forget about heat distribution
Why? Some components may get really hot and you may need to place there heatsink or find another way how to take the heat away.
TIP #019: Always be sure that pin numbers are pointing to ...
Why? Because it’s one of the silly mistakes which you can make while creating a new component. It is often very hard to find and fix.
TIP #018: Always create a BOX around ribbon cable headers
Why? You need space for mating connector and you may use boxed and unboxed version of header
TIP #017: For complex boards, build at least 3 to 5 prototypes
Why? Many times, there may be something wrong from assembling process or you may damage some boards during testing.
TIP #016: Using series termination resistors may help
Why? It will slow down the signal edge.
TIP #015: Create a TODO file to list the future changes
Why? It helps you to remember the changes in the next revision
