High Current 0.8mm 38 Pin BTB Connector Plug Curved Terminals PCB Board-to-Board Connector Mylar SMT Gold Ni Contact Finish

Product Highlights

✅ Blind‑Mating & Self‑Alignment Tolerance Design: Built‑in guiding chamfer structure, absorbs minor assembly offset, avoids pin damage during automated pick‑&‑place mating, reduces assembly scrap rate

✅ High‑Speed Signal Integrity: Impedance‑optimized curved contact terminals, stable performance for high‑speed differential signal transmission, minimizes insertion loss & crosstalk.

✅ Defined Mated Height: Precise stacked mated height control, consistent PCB stack‑up dimension for your mechanical enclosure design.

✅ High‑Current Curved Terminals: Copper‑alloy curved contact beam, reliable multi‑point contact, sustains stable power & signal transmission.

✅ SMT with Mylar Tape: Mylar carrier tape prevents terminal deformation during reflow soldering, fits mass‑production SMT assembly lines.

✅ Gold‑Nickel Contact Finish: Gold plating on mating area + nickel under‑layer, anti‑oxidation, low & stable contact resistance for long service life

Product Description

Cross‑Reference / Alternative

This 0.8 mm 38‑pin curved‑terminal BTB plug is engineered as a drop‑in functional alternative for selected Molex SlimStack®, JAE, Amphenol BergStak® 0.8 mm series BTB plugs.

• Matches critical footprint, mated height, electrical & mechanical performance for direct replacement in existing PCB projects.
• No PCB layout revision required for most cases; please verify the dimension drawing before mass production.
• Cost‑optimized lead‑time advantage vs original imported components for volume projects.

Product Feature

1. Curved spring‑beam terminals deliver stable multi‑point contact, resist vibration & thermal‑cycle stress.
2. Self‑alignment blind‑mating chamfer guards pins against mis‑insertion damage for auto‑assembly production.
3. Mylar backing tape holds fine‑pitch terminals coplanar, prevents distortion during tape‑reel transport & reflow.
4. Gold‑over‑nickel plating maintains low contact resistance even in humid or slightly corrosive working environments.
5. Compact 0.8 mm high‑density pitch saves valuable PCB stacking space.
6. Strict coplanarity control for zero‑defect SMT pick‑and‑place yields.
