When working with TSSOP (Thin Shrink Small Outline Package) ICs in SMT assembly, selecting the right packaging method is key to efficiency, component protection, and production quality. Let’s explore tape & reel, tray, and tube packaging options, their benefits, and best practices for handling TSSOP ICs—so you can make the best choice for your production line.
What is a TSSOP Package?
Thin Shrink Small Outline Package (TSSOP) is a popular surface-mount IC package used in SMT assembly. Its compact size and fine lead pitch make it ideal for high-density PCB layouts, consumer electronics, industrial control boards, and IoT devices. But also requires careful handling to avoid bent pins or damage during assembly.

Tape and Reel Packaging for TSSOP ICs
Tape & Reel packaging is the go-to choice for high-volume automated SMT production. Components are placed in embossed pockets along a continuous tape and wound onto reels ready for pick-and-place machines.
Why Choose Tape & Reel?
- Perfect for fast-paced production lines
- Reduces manual handling, minimizing risk of bent leads
- Works seamlessly with most SMT equipment
Tray Packaging for TSSOP ICs
Tray packaging is ideal for prototyping or low-volume production. Components are securely held in trays, minimizing movement and reducing the risk of damage. This packaging is often used for high-precision or sensitive ICs. Additionally, trays make visual inspection or automated testing (such as AOI or functional tests) easier, since the ICs are neatly arranged.
Why choose tray packaging?
- Maximum protection for fragile IC leads
- Easier manual handling and inspection
- Great for small or customized production runs
Tube packaging for TSSOP ICs
Tube packaging is another common option for through-hole or TSSOP ICs, especially when handling medium-volume production or shipping ICs in bulk. ICs are placed in rigid or semi-rigid plastic tubes, which keep them aligned and protected during transport.
Why choose tube packaging?
- Simple and cost-effective for medium production
- Protects IC leads reasonably well
- Easy to store, transport, and handle

Tips for Handling TSSOP ICs from Tape or Tray
Anti-static precautions: Use ESD mats and wrist straps to protect components.
Storage: Keep ICs in a dry and cool environment to prevent moisture damage.
Transport: Avoid stacking heavy trays or dropping reels.
Inspection: Check for bent leads or damaged tape/trays before assembly.
Other Considerations
Moisture Sensitivity: Some TSSOP ICs are moisture-sensitive. Baking may be required before soldering.
Orientation: Ensure correct IC orientation when loading tape or tray into pick-and-place machines.
Lead Pitch: Small lead pitches need careful handling to avoid shorts or misalignment.
