SH260 Polyimide PCB
Shengyi SH260, ISOLA 370HR / IS410 / IS420 in Stock | Stable for Burn-in, Down-hole & Aerospace

Overview
SH260 is rigid polyimide PCB raw material by ShengYi Technology, a high-performance polyimide laminate and prepreg for PCB raw material.
With Tg >250°C and Td 429°C, SH260 is the benchmark for sustained high-temperature PCBs — built for boards that run hot for the long haul in burn-in, down-hole and aerospace environments.
Andwin keeps Shengyi SH260 laminate in safety stock for short lead times, and provides engineering support for stack-up, impedance and DFM review.

Why SH260 polyimide PCB
Features of SH260 polyimide PCB
Engineered for heavy-industry RF environments where ordinary PCBs fall short.
Tg >250°C — stays stable where standard high-Tg FR-4 fails.
Td 429°C — survives harsh thermal profiles and lead-free reflow.
Benchmark material for sustained high-temperature PCB service.
Track 3/3 mil and HDI capability for dense polyimide stacks (per page).
Controlled-impedance stacks with TDR testing on critical nets (per page).

Frequently Asked Questions
1. What materials do you use for high-temperature PCBs?
We build with Shengyi SH260 polyimide (Tg >250°C, Td 429°C) and ISOLA high-Tg laminates (370HR / IS410 / IS420). SH260 leads when the board must run hot continuously; ISOLA is the cost-effective high-Tg choice.
2. What is the lead time for high-Tg PCB prototypes?
With SH260 and ISOLA laminates in safety stock, prototype turnaround is short — typically 7–12 days depending on layer count, via structure and surface finish.
3. Can you build polyimide multilayer and HDI boards?
Yes. We run high layer-count polyimide stacks and HDI (3/3 mil tracks, micro-vias) on SH260, with tight thickness control and reliable plated through-holes.
4. Can you control impedance on high-Tg materials?
Yes. We provide controlled-impedance stacks and TDR testing with ±5% tolerance on critical nets; ISOLA 370HR / IS410 are well suited to controlled-impedance digital designs.
5. What is your minimum order quantity (MOQ)?
No MOQ for prototypes — order as few as 5 pieces. Production pricing starts at 50 pieces.
