TIP #028: When you are looking for a component, you may want to start your search at a supplier website
Why? It compares components between more manufacturers and
shows a lot of important information such: price, available stock or minimum order quantity

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: If you are new in memory layout, 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 #024: Place Reference point (the x=0,y=0 point) of a footprint for …

TIP #024: Place Reference point (the x=0,y=0 point) of a footprint for SMT components to the middle of the component or consider to place it into center of gravity.
Why? This reference point is very often used in Pick & Place output files. This means, when doing assembling, machine will pick up the component at this 0,0 position.

TIP #022: Place ESD protection as close as possible 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, otherwise your board may not work properly.

TIP #019: Always be sure that the pin numbers in schematic are pointing to …

TIP #019: Always be sure that the pin numbers in schematic are pointing to the right pins in footprint
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 (many times, board has to be redesigned).

TIP #018: Always create a BOX around the ribbon cable headers

Why?
– you need space for mating connector
– you may use boxed and unboxed version of header

TIP #017: For complex boards, always build minimum 3, but rather 5 prototypes

Why? Many times, there may be something wrong from assembling process or you may damage some boards during testing.
