PCB Tips

 

Accepted File Formats

Gerber RS-274X is preferred although we can accept RS-274D and ODB++ formats. read more...

 

Array Design

The primary reason for having your boards delivered in an array is to make automated assembly faster and less expensive. Running an array of boards through a pick-and-place machine is far more efficient than sending them through one at a time. Arrays are read more...

 

Controlled Dielectric or Controlled Impedance?

What is the difference between Controlled Dielectric and Controlled Impedance regarding PCB fabrication? The purpose of controlling dielectric or impedance is essentially the same, to achieve a target impedance on one or more signal lines on a printed read more...

 

Copper Thickness FAQ

The most common unit of measure for the copper thickness on a printed circuit board is ounces (oz). But how thick is that? It's the resulting thickness when 1 oz of copper is pressed flat and spread evenly over a one square foot area. This equals 1.37 read more...

 

Countersink vs Counterbore

Countersinks and counterbores serve the same purpose, to allow the head of a screw or other fastener to lie flush with, or just below the surface of the material they are inserted into. The difference between them... read more...

 

Dielectric Stacks

Dielectric Stack visual displays... read more...

 

Drilling and Drill File

What is the difference between a hole and via on my printed circuit board? Essentially they are the same thing and many engineers use the terms interchangeably. read more...

 

Final Finish Comparison

There are many factors to consider when selecting a final finish for your printed circuit board. read more...

 

Rigid Specifications

We don't need much information to manufacture a bare printed circuit board. Often, all we receive are the digital Gerber files showing the copper layers, solder mask, silk screen and a drill file. When we are given no other information, we'll assume the read more...

 

Solder Mask

Solder Mask is a protective coating applied to the bare printed circuit board. Bare boards are covered with mask to prevent accidental solder bridging during assembly and to help protect the board from the environment. read more...

 

Via Tenting, Plugging, and Filling

There are many reasons a printed circuit board designer might want to have a via tented, plugged or filled. First, let's start with defining these terms since they can be frequently misused and misunderstood. read more...
