MIL SPEC is the favored supplier for many technology companies for both production and prototype quantity work. Our clients have the choice of supplying the materials for prototypes, or asking MIL SPEC to acquire the materials.

Our size and company structure allow us to be flexible and highly responsive.

We understand an engineer cannot wait weeks to receive and test a new prototype design. As such if you’re in Houston, at no charge, we will pick up your engineering parts kit, any day or time of the week, and hand deliver the finished product back to you – any day or time of the week that will meet your needs.

Regardless of your location, if you need a prototype, delivered or shipped on weekend for a hot test project, let us know.We will make it happen.

The use of High-lead, High Melting Point solder ( HMP and Gold) has significant challenges that require a specialized skill-set, and an equally important sense of discipline to properly utilize in high-temperature circuit board applications.

The very metallurgy of HMP solder, typically 85-93% Lead, creates a condition whereupon the solder resists flowing uniformly and completely, especially when applied to Plated-Through-Hole (PTH) connections which create a greater heat sink effect than SMT components.

On top of these difficulties let’s also add the most common mistake that other CM’s make on PTH components – feeding HMP solder from both sides of the board which creates a cavity of unburned flux and air in the center of the via. At high temperatures this via’s connection will absolutely fail. HMP solder must only be fed in from the Secondary Side.

The skill becomes imperative in knowing the correct tip temperature, contact duration, and rate of solder-wire feed to create a one-touch, complete, solder joint without reheating the solder joint a second time which creates a brittle, unreliable solder connection. This brittle connection will have a low mechanical adhesion strength and will most likely fail when the PCB is exposed to the shake and vibration of the downhole environment.

Think about this – a $3 dollar part in a $5 million dollar downhole tool, on a $250,000 a-day rig can fail due to a single, unreliable, solder joint.

Despite the requirement for these critical soldering techniques and disciplines, our third-party inspection service routinely inspects assemblies from other CM’s that show the telltale evidence of reheated solder joints.

At MIL SPEC we wrote the book on High Temperature soldering.

HMP is its own world. It requires very specific knowledge, techniques, tools, - and patience.

We seek to create genuine partnerships with our clients. One of the ways we do this is to collaborate in the area of Design For Manufacturing (DFM).

At no charge, we will review a client’s PCB layout before it is built to make layout suggestions that help to reduce manufacturing times (and therefore cost), and increase the reliability of the finished product.

Our clients and MIL SPEC both benefit from this practice.
