Products · Hot-bar · T / DK
T and DK faces: a narrow contact and a way past the body.
A T face concentrates the pulse on a narrow tab. A DK face does the same while leaving a clearance beside a component that must not be touched. Both are about directing heat, not spreading it.

What it is
Heat where the tab is, clearance where it is not.
Connector bonding often fails because the tool heats more than the tab: the housing softens, the adjacent pin reflows, or the tool rests on a body it was never meant to touch. A T face limits the contact to the tab; a DK face adds a relief that clears the body entirely.
The relief is as important as the contact. It is machined to the drawing, not guessed from a photograph, because a 0.2 mm error can mean the difference between clearance and interference on a moulded housing.
Published geometries
T / DK codes, faces and typical joints.
Face width is quoted as the class for that code. The exact A/B/C/D dimensions for a specific part number are issued with the quotation, not estimated on the page.
| Code | Face | Working width | Typical joint |
|---|---|---|---|
| T-0.8 | T | 0.8 mm contact | Fine connector tab |
| T-1.0 | T | 1.0 mm contact | Standard tab |
| T-1.5 | T | 1.5 mm contact | Wide tab |
| DK-1.5 | DK | 1.5 mm contact + relief | Tab beside a housing |
| DK-2.0 | DK | 2.0 mm contact + relief | Wider tab, tight clearance |
| DK-3.0 | DK | 3.0 mm contact + relief | Heavy tab |
Codes are listed by face family. Variants with a different width, bend or reach are ground to order; send the drawing or the joint photograph and we will confirm the code.
Compatibility
What it fits — and what to check.
| Machine or holder | Interface | Note |
|---|---|---|
| Connector bonder | T face | Confirm tab width |
| Hot-bar bonder | DK face | Confirm relief depth |
| FPC bonder | V or U face | Use V/U series |
Model names describe the machine a part fits. XANJO replacement parts are independent parts, not original equipment manufacturer parts.
Dimensions
Four numbers define the part.
A is the overall length from the seat to the working face. B is the shank or body diameter. C is the width of the working face. D is the reach from the seat reference to the face — the number that decides whether the part can touch the joint without the housing fouling the board.
We hold ±0.05 mm on the shank and seat, and we issue the drawing revision with every batch. If a dimension is not measured, it does not go on the drawing: that is why some codes are marked “drawing on request” rather than filled with an estimate.
Ordering
Samples, minimums and lead time.
T and DK profiles are machined to the drawing; relief depth is confirmed before the face is lapped.

Questions we are asked
T / DK fitting and ordering.
How much clearance does a DK face need?
Enough to clear the tallest part beside the tab with the tool at the bottom of its stroke. Send the component height and the tool travel; the relief is dimensioned from those two numbers.
Can a T face be used on a flexible tab?
Yes, if the tab is supported underneath. A narrow contact on an unsupported flex can bend the tab instead of bonding it.
Do you make the mount to match my machine?
Yes. The mount is part of the drawing: stud, collar or clamp, with the body height and the flat position stated.
Are these OEM parts?
No. XANJO thermodes are independent replacement tools.

If this is not your machine.
Send the part number. We’ll send the drawing.
A code, a machine model or a photograph of the holder is enough. We reply with the geometry, the A/B/C/D drawing and the specification within one working day.
