How to Clean and Restore Mobile Devices and PCBs

The Best Way to Clean PCBs

The PCB market is expected to reach an estimated $89.7 billion by 2024 with a CAGR of 4.3% from 2019 to 2024 according to a report by Lucintel.  Important to both manufacturing and maintaining PCBs is keeping them clean.  Delicate PCB circuitry is affected by contaminants introduced during fabrication and by exposure to moisture and other elements in daily use. This post explains why fabricators, computer and mobile device repair services use ultrasonic cleaners as the best way to clean PCBs. 

Why Ultrasonic Cleaning is the Best Way to Clean PCBs

If you manufacture PCBs, sell or repair mobile devices or other products utilizing printed circuit boards  an ultrasonic cleaner should be part of your equipment inventory. Unlike potentially damaging mechanical cleaning PCBs with brushes and solvents, these units use the power of ultrasonic cavitation  to quickly, thoroughly and safely remove contaminants from all surfaces immersed in a biodegradable ultrasonic cleaning solution.

Ultrasonic Cleaning to Remove 3D Printing Mold Support

Use Ultrasonic Energy to Remove 3D Printing Mold Support

Ultrasonic cleaning is fast and safe way to remove mold support and other surface contaminants from simple and complex 3-D printed parts.  Results are far superior to time-consuming water soaking and the risk of possibly damaging part geometries if manually cleaned using brushes.  Here you’ll learn how 3-D printed parts are made, then how ultrasonic energy is used to remove 3D printing mold support from your parts.

How 3-D Printed Parts are Made

3D part printing techniques use a variety of plastics and resins.  Examples include ABS, PLA, polyamide (nylon), glass filled polyamide, stereolithography materials (epoxy resins), silver, titanium, steel, wax, photopolymers and polycarbonate.   

A popular technique combines two moldable thermoplastic formulations such as ABS for the part itself and PLA for removable mold support.  This is a quick means to produce highly complex configurations.

In this instance a key to the efficiency of the process is fast, safe removal of the PLA mold support without risking damage to the ABS part.  An ultrasonic cleaner is proven far faster, safer and more effective than water sprays or manual scrubbing.

Other techniques called SLA (stereolithography) and LFS (low force stereolithography) use lasers to build the part without the need of mold support. In these cases uncured resin on the finished product requires removal best accomplished by ultrasonic energy.

How Can I Use Flammable Solvents in an Ultrasonic Cleaner?

First, let us congratulate you for asking this question.  Any time flammable solvents are used for cleaning purposes there is risk of fire or explosion due to ignition of volatile vapors by a flash source.  Ignition can occur from any source due to spills or as flammable solvent vapors spread.  This post explains how you can safely use flammable solvents in an ultrasonic cleaner.    

An example of a widely used flammable solvent is isopropyl alcohol (IPA).  References to its use are presented in this post.

Things to Know about Flammable Solvents and Ultrasonic Cleaners

Before you select and use an ultrasonic cleaner for your application(s) you should be familiar with options available as well as other factors that go into the decision process.  Here you will learn about 

  • the definition of “flash points”
  • flash points of commonly used flammable solvents
  • where ultrasonic cleaners are used with flammable solvents
  • ultrasonic equipment options when cleaning with flammable solvents
  • other safety precautions when using flammable solvents in an ultrasonic cleaner
