Conformal Coating Service

Why apply conformal coating?

Printed Circuit Boards (PCB) is the core of everyday life as most electrical devices can not function without one. From everyday life to military and medical situations, a PCB must be able to withstand the wear and tear of time and other elements. Conformal coating is designed to protect Printed Circuit Board (PCB), and related equipment from their environment. Typically applied at 0.001 inches to 0.003 inches on the PCB. It is a protective nonconductive dielectric layer that is applied to the assembled printed circuit boards to protect the electronic product from damage due to contamination, salt spray, moisture, fungus, dust, and corrosion caused by the harsh or extreme environment.

Solder Mask on Printed Circuit BoardsACME PCB Assembly happens to offer three different kinds of conformal coating for our valuable customers. The acrylic conformal coating is a low viscosity coating that is cured through drying and isn’t too resistant to chemicals but hardens quickly. The Urethane conformal coating is also a low viscosity coating, however, is cured through crosslinking with strong resistances to chemicals. Silicone conformal coating is a very viscous coating that is applied through swirl technology with high chemical resistances.

Below is a graph that shows the characteristics of the conformal coatings ACME PCB Assembly provides.

Printed Circuit Boards

Is it Possible to Recycle Your Unused Printed Circuit Boards?

We will be discussing the issue of PCB recycling, if it’s even possible, how it is done and what can we do as electronics design engineers to create more recyclable PCBs. When we say PCB we are meaning a PCB without any components on it.  Most electronic devices found out there have their components sitting in a nice looking Printed Circuit Board or PCB.  Since electronic devices are in high demand, PCBs are everywhere. Making sure their materials can be collected and reused instead of just throwing them into a landfill would potentially be a smart and environmentally sensible move if performed properly.

Remember that large order of printed circuit boards you ordered? You thought it would be a good idea to have a surplus of parts on hand in case you needed to increase production of your product line. Unfortunately, that product got discontinued, so now you have a huge stash of PCBs taking up room in your warehouse and on your accounting books. It is time to trash them?

Not so fast! In many cases, printed circuit boards can be reworked and modified. Do you have another electronic or computerized product in the works? Then contact ACME PCB Assembly  we may be able to re-purpose your PCBs. Our workers are highly trained in de-soldering and re-soldering surface mounted electronic components. We have also invested in specialized equipment that can assist us in these efforts.

Can you recycle your old PCB?

Yes and no, before coming to a final decision let’s first see what a PCB is made of. A PCB is basically a layered sandwich of copper and FR-4. FR-4 is a fiberglass with an epoxy resin that has the purpose of bonding the fiber together and as an adhesive, it is also flame resistant. Apart from that, you can also find tin and small traces of gold and silver.

Don’t throw out unused printed circuit boards.

Wire Harness

ACME PCB Assembly Wire and Cable Harness Services

It is important to understand that a wire harness is different than a cable harness.  A wire is a single conductor, while cables are two or more wires that are insulated being wrapped in a larger jacket. These two technologies demand their own set of unique tools, fixtures, and machinery to help reduce production costs. Knowing exactly what type of product being used is crucial to perfectly create your designs.

Wire harnesses generally do not need much to work with and is generally an inexpensive and cost-efficient way for many people to solve their electrical needs. With a single machine, one can increase their production capabilities because of the relative simplicity of wires in general.

A wire harness is a method that incorporates several point-to-point cable assemblies together into one conclusive assembly.  They are generally held together using cable ties or some form of protective sleeve used to protect the wires or cables from environmental conditions like moisture, heat or friction, and to organize the different breakouts for easy routing through a system or box build.

What Can Wire Harnesses be Used For?

Though you might confuse a wire harness for a cable assembly, there is one main difference and that is a wire harnesses usually contains several ends or breakouts, running in different directions, serving multiple functions with multiple terminations on each breakout.

A custom wire harness can be used in durable goods like household appliances, in and around engines of all kinds – automobiles, buses, locomotives, trucks, and even planes.  Electronic equipment, construction machinery, industrial equipment, HVAC products all use wire harnesses as well.
