Colorful PCBs Does Solder Mask Hue Impact Functionality- Circuit Board Assembly

Traditionally, circuit boards are green. But today's world is more diverse -- even when it comes to PCBs! Although green boards are still popular, many PCB assembly services now offer a variety of solder mask colors to customers. What does this mean for the PCB fabrication and Circuit Board Assembly process? And can you expect to receive all different hues of PCBs when you place an order for circuit board assembly services? We'll discuss this colorful topic in today's post. In years past, PCB solder mask was almost exclusively green There are a few reasons for this. One is that [...]

Why You Need 3D X-Ray Testing- Printed Circuit Board Assembly-Hitech PCB

Printed circuit board assembly has come a long way in recent years. Now that PCB assembly can easily be performed by machine, PCB manufacturers have been able to increase their production and drastically reduce the time required for this process. In fact, a few PCB assemblers even offer standard turnaround times of three days or less -- 75% faster than the industry average. However, clients who rely on these circuit boards will never be willing to sacrifice quality for speed. In order to ensure PCB production maintains a high-quality standard and exceeds customer expectations, PCB assemblers must prioritize testing during [...]

Something About Heavy Copper PCBs

Heavy Copper PCBs are printed circuit boards featuring copper conductors 3 oz/ft2 – 10 oz/ft2 in inner or outer layers. These printed circuit boards are valued immensely, due to their thermal management capabilities. When heavier copper is electroplated to the PCB, it ensures high reliability and efficient power distribution. This post discusses heavy copper PCBs in detail.   Advantages of Heavy Copper PCB   Heavy copper PCBs are normally used in high power transmission applications due to several advantages they offer. Let us look at few of them.   Heavy base copper allows delivery of consistent and reliable power. The [...]

Electrostatic Discharge and Its Effect on PCBs- Advanced PCB Assembly-Hitech PCB

If you've decided on a source for PCB assembly services, you'll already know how intricate this work can be. PCB designers use computer-based design software to design a board's circuit pattern. The spaces between these electrical conducting paths are often smaller than 0.04 inches in size. This production requires precise work; unfortunately, the integrity of a PCB can be compromised with any minuscule mistake or even a tiny change in the environment.   What is ESD and what causes it? ESD, or electrostatic discharge, refers to what occurs when two objects with opposing charges come into contact with one another. [...]

Common Issues You Should Avoid When Transitioning to Machine PCB Assembly- PCB fabrication

Making any kind of change can come with its fair share of frustrations and pitfalls, but those issues can just about double when it comes to change in a highly technical industry like printed circuit board (PCB) fabrication. So when it comes time for you to make the switch from hand-made PCBs to automated PCB assembly, it's important to know what you're up against. Are you ready to learn what to watch out for during this tricky transition? If you answered yes, keep reading.   Lack of Silkscreen When the time comes for you to make the move to automated [...]

Why Rapid PCB Prototyping is so Important?

Why Rapid PCB Prototyping is so Important? As the need for manufacturers to increase their time-to-market speed increases, the need for faster PCB prototyping also increases. Rapid Printed Circuit Board Prototyping is usually the step that takes the longest in the whole process and, as such, needs to be shortened in practical ways because new software and features can only be tested out on prototypes. Let’s take a more in-depth look at why rapid PCB prototyping is so important. Short Turnarounds The best express PCB prototyping methods all have one thing in common: short turnaround times. This means that new [...]

Types of PCB Failure analysis test

1.Micro-Sectioning Analysis Micro-sectioning also know has cross-sectioning or metallographic preparations are used for PCB testing. Thermo-mechanical failures Component Defects Opens or shorts Processing failure due to solder reflow Raw material evaluations   2.Solderability Testing Solderability test work for a variety of applications and quality standards PCB Coating Evaluation Solder Evaluation Flux Evaluation Benchmarking Quality control The PCB failure analyst should have the experience to differentiate the various conditions and understand the requirements of the testing technique   3.PCB Contamination Testing Contaminations can be the reason for part failure including degradation metallization Processing of printed circuit boards is taken place in [...]

Common PCB Fabrication Mistakes, and How to Fix Them

A prototype printed circuit board fabrication is an electronic circuit that can be used for a variety of reasons. A typical PCB layout consists of up to 36 layers, and the most simple prototype PCBs contain copper tracks that interconnect with each other on only one of its surfaces, known as 1 layer PCB.   Considering that PCB fabrication can be a bit complicated with all those layers, the potential for mistakes is large. Mistakes can cause short circuiting and circuit board failure, and they are most often due to poor planning during the PCB fabrication process. So in order [...]
