Silver plating for lugs: high-current joints
Silver gives the lowest contact resistance of the common lug finishes. It also tarnishes, migrates and costs more. Where it earns the premium.

Braid weld pull test
A pull test proves the weld, not the braid. Sample size, grip position, pull rate and failure location all decide whether the number means anything.

Cable lugs for 1.5 to 630 mm²: a sizing table
A conductor range is not a part number. How to read a lug size chart, what changes across the bands and which details the chart cannot decide.

DIN 46234 lugs: what the standard covers
The scope, dimensions and limits of the sheet metal solderless terminal, and why it is not a drop-in replacement for a DIN 46235 compression lug.

Heat sinks for medical and lab equipment: cleanability and quiet operation
How to choose a cooling route when the room has to stay quiet, the surfaces have to be wiped down and the airflow path must not become a harbour for dust.

Terminal material: copper, brass and phosphor bronze
Conductivity, clamping strength and spring are three different jobs. The material that wins on one can lose on another, and the section often settles the argument.

Tin plating for lugs: thickness and corrosion
Tin is the default finish on copper and brass lugs. The thickness callout, the corrosion behaviour and the checks that stop a cosmetic flash being accepted.

Braid millivolt drop testing
A millivolt drop test is the quickest way to prove a braid joint. The result depends entirely on where the probes sit, how much current flows and when the reading is taken.

Copper vs brass lugs: conductivity and strength
Brass is stronger and cheaper to machine. Copper carries current better. Where the trade is safe, and where a brass lug becomes a hot joint.

Lug and terminal defects: cracks, plating, thread and crimp
The four defect families that cause most lug rejections, how each is detected, and where to fix the process instead of sorting the output.

Machined parts for RF and microwave: finish, conductivity and geometry
Why a machined RF housing is judged on the surface inside the cavity, the flatness of every joint and the plating on the current path.

Terminal plating: tin, nickel and silver
The finish has to protect the surface, hold contact resistance and survive the crimp. A comparison of the three common coatings and the callouts that make them inspectable.

Go from reading to checking
The guides are built around the same questions as the free tools. Size a busbar, check an ISO 2768 callout, build a first article report or compare landed cost.
