- Cut-off Burr/Nib
- A small remnant of material left behind on a part as a byproduct of machining. Typically located on the face being cut to separate from the remaining bar stock. Cleaning & deburring operations help to smooth out this bump/protrusion. In applications which require more of a flush surface, the cut-off can be delegated to the less critical side of the part or removed by making a small indent in its place.
- Surface Mount (SMT)
Mounting style in which parts are assembled onto a flat pad/land on the PCB. Mill-Max offers two styles of surface mount features – either a flat bottom base or bent “gull wing” style tails. Surface mount parts are well-suited for automated, high volume builds which use pick & place equipment and controlled soldering processes such as intrusive reflow and pin-in-paste.
In addition to vertical surface mounting, horizontal surface mount (HSMT) parts can be soldered to a pad/land in a parallel fashion for engagement from the side. HSMT parts are also offered in two styles – a flat surface base or bent tails, referred to as “z-bend” tails in the horizontal configuration. View examples
- Pin Grid Array (PGA)
A type of processor packaging which offers high-position, customizable arrays of pin/receptacle connections spaced .100” (2.54mm) apart and housed in a square or rectangular insulator. Mill-Max offers PGA style headers, sockets, and carriers for surface mounting, through-hole mounting, or wire-wrap termination. View Examples
- Edge Mount
A pin termination style which captures the edge of a PCB with a solder connection or mechanical fastener. These pins often have a tail to allow perpendicular connection with another board or device. Useful in applications where a circuit board needs to be cyclable, such as in mother-daughter card applications. View Examples
- Daisy Chain
Interconnect components mated horizontally in series to form a longer sequence. Most often performed to bridge a gap between boards or extend the connectivity of a device using horizontal mount header & socket combinations. Certain spring-loaded connectors can also be used for daisy chaining by mating the plungers of one against the bases of another.
- Kapton
A polyimide film used to package and transport discrete interconnect components. Commonly used for semi-automated board assembly. View Example
- Jumper
A pin that is bent into a U-shape whose primary function is to bypass or connect a pair of uncoupled traces on a circuit board. These pins are currently offered discrete or assembled into insulated housings. View Examples
- Inspection Hole
A hole drilled on the side of certain wire termination parts which provides internal visibility. This can be used to verify that a wire has been successfully assembled to the part, whether by a crimping or soldering operation. View Examples
- Closed Frame
A type of DIP insulated housing that does not include an open mid-section or window. This solid surface makes the connector better suited for automated handling such as with a vacuum nozzle. View Examples
- Packaging
- The method by which finished goods are enclosed and shipped to customers. Most discrete Mill-Max products are provided in bulk, which involves packaging the products in either sealed plastic bags, tubes, or cushioned boxes. However, more automation friendly options are provided as a value-added process; these include Kapton tape, tape and reel, and trays.
