“Laser” stands for Light Amplification by Stimulated Emission of Radiation. Simply put, laser welding uses a laser's energy to generate heat in a focused beam. The beam is focused on a designated area, and energy is then pulsed through the beam and directed at that area. The beam causes the metal or metals to heat and melt at the point of the target, or “weld”. In their [...] Read More
In 1970, when Accumet Engineering Corporation first opened its doors, the American landscape was post-industrial, but pre-automation. But in a small factory in Hudson, Massachusetts, the future of American manufacturing was being engineered by a handful of forward-thinkers.
Our accomplishments over the last 50 years include:
* Moving from paper job tickers and spreadsheets of the past to a [...] Read More
In 1965, Intel co-founder Gordon Moore predicted, based on careful observations of emerging technological trends, the steady, two-year cadence of chip improvements that would double a processor's performance every couple of years, while simultaneously decreasing its relative cost. While far from prophetic, “Moore's Law”, as it came to be known, would hold true for decades, and serve [...] Read More
When we say the word absorbers, you can intuit its meaning from the "absorb" base of the word: absorbers absorb things. Think of sponges: they absorb water or other liquids. Absorbers in the RF/microwave world are used in a wide range of applications to absorb and thereby eliminate stray or unwanted radiation that could interfere with the operation of a system or device. Elements [...] Read More
Lapping and Polishing are processes which are performed to achieve a desired surfaced finish, thickness, parallelism and flatness of any substrate.

When plating through holes in a printed circuit board, sometimes vias are filled irregularly. The result is raised bumps along surface of board. There was a time where this was not a problem, but in the age of surface mount components, surface planarity is critical. This is because adjacent, low-profile components may be affected by the surplice of metal.
How can Accumet help with via filling?

Product manufacturers may wish to consider laser marking as an alternative to screen printing (also called silk screening) when looking to permanently mark a surface such as with a bar code, a serial number, a logo, or calibration settings. Depending on the application, laser marking and screen printing each have their pluses and minuses — although for most applications laser marking is faster, [...] Read More
Laser ablation is a process that product manufacturers may wish to consider when looking to remove unwanted materials from a part’s surface or when they wish to control solder flow on a PCB — typically so excess solder does not travel where it’s not supposed to and cause electrical shorting. For cleaning a surface the technology that laser ablation typically replaces is chemical milling. [...] Read More
Each method has its relative pluses and minuses and no one method fits every situation. The thickness of the stock to be cut, hardness of the stock, whether or not the stock is stacked or layered, your cost and timing requirements, and the desired condition of the material after it’s been cut are among the key factors that determine which method is right for a particular job. There are also some [...] Read More
When the object you wish to engrave has a circumference, the method of choice is typically rotary engraving, especially if you wish to engrave the object on more than one side. It is usually far easier to rotate the object on a spindle than it is to rotate the engraving equipment around the object. Most rotary engraving falls into one of two broad camps. One is mechanical rotary engraving, in which [...] Read More
Product designers and process engineers considering laser welding as an alternative to more conventional types of welding, such as MIG/TIG arc welding, will find each has its plusses and minuses. But for many applications laser welding is a cleaner, more precise, and more controlled method of welding and is especially useful when looking to bond small, thin materials such as medical tools, foils, and [...] Read More

Without the right laser choices and expertise a job shop might set you up to accept limitations you might not have to, take twice as long to process a job, could aid in you failing incoming visual inspections, provide limited bond strength, and ultimately create lower yields and higher costs. “Trying it” on an ill-equipped laser, in other words, is not something you want to endure.
But [...] Read More
From bio implants, to surgical instruments, to lab equipment, and more, a wide range of products in the medical field have very similar requirements when it comes to welding medical devices.
Here’s a question: If you manufacture devices, tools, instruments, or appliances for the medical industry - whether for the surgical suite, hospital lab, medical clinic, dental office, or other [...] Read More

- Are the materials, [...] Read More
If you’re looking to engrave a barcode, serial number, photograph, piece of artwork, a logo, or some decorative lettering onto a curved object, then laser rotary engraving is your best option. Mechanical rotary engraving methods such as diamond dragging, stamping or dot peening tend to be slower, require more setup time, and are more limited in the variety of patterns they can engrave. Lasers [...] Read More
Invented in 1960, the laser was introduced to the plant floor just five years later when the first production laser-cutting machine was used to drill holes in diamond dies. But even though lasers have had a long and successful history in manufacturing, people still have a lot of questions about them in that role. So we thought it would be helpful to have our resident expert, Laser Man, answer the top [...] Read More
Laser welding is much cleaner than conventional arc or Tig welding, and therefore helps risk of contamination. It’s also more precise, easier to automate, and provides for bonding of much thinner metals, and provides for much greater tensile and bending strength.
If arc welding is typically part of your product manufacturing process you may wish to consider laser welding instead. Unlike [...] Read More
When you see BYOB on a party invitation, you know what your host wants you to do. And when you have a BYOD policy at work, you know your boss wants you to bring your own device (smartphone or laptop) to the office. Both BYOB and BYOD are very popular. So what about BYOL? Is buying your own laser a good idea too?
For most manufacturers, probably not, and here’s why:
BYOL Carries Costs and [...] Read More

If you are a product manufacturer how do you know which technology is a better way to cut your materials: laser cutting or water jet cutting? (We covered the relative merits of a third technology, die cutting, in another blog article.) As with most things in life, no one answer fits every situation. The thickness of the material to be cut, your cost and timing requirements, and the desired condition [...] Read More

Here are 3 Simple Reasons the Laser is King Over DIE Cutting
You see, the thing about laser cutting is, well, it’s not just one thing – unless we’re referring to the monochromatic, coherent, collimated power surge generated by the light beam itself – but let’s not delve into a physics lesson here. We might find ourselves lost in the land of limits, summations, [...] Read More
