{{alert.MSG}}

This wire shape/size cannot be produced.

Please select a thinner wire, wider anchor pitch, longer center wire length(in case of Type-S), and/or different clip shape.

If none of these options are acceptable, please contact Alpha Sales.

The anchor to anchor line must run through the circular area. (Also, the length of the line section in contact with the circular area must be at least 90% of the circle’s diameter)

Please specify a different anchor location. If this is not an option, please contact Alpha Sales.

Out of range assymetric error

There is no compatible anchor pin, based on the PCB thicknes, chip height, base thickness and wire diameter.

The maximum dimension for [PCB thickness] + [Chip height] + [Base thickness] + [Wire Diameter] is 15.4mm. A custom clip is required if this dimension is exceeded.

Based on your inputs, this dimension is {{NO_COMPATIBLE_ANCHOR_LENGTH }}(mm).

Please contact Alpha sales for for additonal options.

There is no compatible anchor pin, based on the PCB thicknes, chip height, base thickness, wire diameter and height limit.

The anchor pin length needs to be longer than [PCB thickness] + [Chip height] + [Base thickness] + [Wire Diameter] + 0.6mm ( = {{NO_COMPATIBLE_ANCHOR_LENGTH_MIN}}), and it must be shorter than [Height limit] + [PCB thickness] - 1.2 ( = {{NO_COMPATIBLE_ANCHOR_LENGTH_WITHHEIGHTLIMIT}}).

There is no compatible anchor pin in this range.

Please contact Alpha sales for for additonal options.

Please choose a longer anchor pin or adjust the heat sink base thickness. If neither option is possible, please contact Alpha Sales.

QSZ Clip Design Tool

If you cannot find a standard clip that will work for your application, we can offer to design a custom clip.

  • Z/S-shaped wire clips for heat sink attachment can be designed in a few simple steps.
  • QSZ clip anchor pins only require 1.8mm diameter holes in the PCB!
  • 3D STEP file can be created/downloaded in minutes.
  • No NRE/Tooling fee is required.
  • Estimated unit cost is $20.00 for 10pcs, $3.00 for 100pcs, and $1.50 for 300pcs.
  • Prototype lead time is about 2 weeks.

Clip Shape
Standard
Type-A
Type-D
Type-S

The "Standard" clip runs closer to the heat sink, reducing interference issues with other components on the PCB.

"Type-A" and "Type-S" clips can offer narrower anchor spacing.

"Type-D" clips are recommended if the anchor pins are located inside the heat sink footprint.

Wire Diameter

The typical clip wire diameter is 1.4mm.

Depending on the clip design and anchor spacing, the attachment force would be 1.5 to 3.5 kgf.

If a higher attachment force is required, a thicker wire diameter can be used. This may require additional heat sink customization, such as fin removal.

A thicker wire can make installation more difficult.

Target Attachment Force

The target attachment force is determined by considering several factors:
These factors include the following: Allowable attachment force specified by the device vendor, pressure required for acceptable thermal interface material performance, and the force required to withstand shock loads.

Target attachment force will be considered a reference value.

This dimension depends on the heat sink fin pattern.

If you are not sure, just enter 10mm and input the heat sink model number.

We will check for any interference issues.
