How do I do point to point wiring on a protoboard?

I bought a small "fancy" protoboard from Sparkfun. It includes a solder mask and through plated holes(double sided). Now I'm trying to do a simple circuit and I can't seem to figure out how to drag solder across the board. The solder mask keeps the…

Soldering with bus wire on perfboard

What's the proper way to solder with bus wire on perfboard. I used perfboard for the first time on a project recently. I designed a great layout and started soldering the components to the copper pads; the joints were perfect and beautiful. Then I…

Adding a small protoboard-like area to a PCB

I'm currently laying out a PCB in eagle for a circuit that will form the basis for some experimentation. Instead of adding a row of headers so that I can plug it into a breadboard, I figured I would try and layout a small protoboard directly onto…

Where can I source extra long headers from

I have recently purchased a sparkfun protoboard that I wish to stack above an ethernet shield. (I have 2 different ethernet shields, an Arduino one and a seeed studio enc28j60 shield.) The problem I have is that if I use the supplied headers, or…

How to fix a PCB inside this enclosure?

This is a related question to How to fix this in an enclosure without glueing. However, for a protoboard/PCB, how could I attach it to the enclosure? The bottom of the enclosure has holes for attaching, but it doesn't have screw thread. How should…

Purpose of perfboards with pads all connected

A while ago I saw a protoboard with the pads all connected; at the time I thought it was a manufacturing glitch, but today I saw another one. I cannot think how these boards may be useful - any ideas? Here they are:

Protoboard components being used for applications with high current

If I have a few pins of a relay (which is rated for the correct current) that will carry 5A when the relay is triggered, what's the best way to wire this up? Details: I have a breadboard with a circuit on it, but a small loop in the circuit will…

How can I determine voltage and current limit of protoboard?

I have a project I want to wire up on a prototype board. I know the peak voltage and current expected at each contact point. But how can I tell whether the board can handle it? If it can't then it will arc (too much voltage) or overheat (too much…

Tips on using a Prototype PCB

Recently I have been trying to get myself an arduino made by hand (as where I live the original one costs about 10x and its fun to make things on your own). I made a compatible on the breadboard and tested it using the blinky program. Now I want to…

Can problems arise from mixing 2.5mm pin pitch components with 2.54mm through-hole protoboards?

I am new to electronics and from what I understand, most protoboards seem to be standardized on a 2.54mm (0.1") pin pitch. I am also aware that there are through-hole components which are manufactured at a 2.5mm pin pitch, namely JST…

Protoboard limitations when dealing with high impedance circuits?

I understand protoboards have several limitations for prototyping circuits. However, most information found deals with parasitic capacitance such as to cause problems with higher frequency circuits. My question is what are the limitations of…
