ALPHA?OM-338-PT 是一款無鉛免清洗錫膏，設計用于多種應用。
ALPHA OM-338-PT 較寬的加工窗口設計用于最大程度減少從錫/鉛到無鉛錫膏的過渡問題。這種材料被設計為具有與錫鉛工藝相媲美的性能。ALPHA OM-338-PT 在多種電路板設計上都能產(chǎn)生出色的印刷能力性能，尤其是在具有超精細特征重復性（11 平方密爾）和高“吞吐量”的應用中。ALPHA OM-338-PT 采用的配方可提供比 OM-338 更高的電路內(nèi)引腳測試良率，同時不會影響電氣可靠性。*盡管這些無鉛合金的外觀與錫鉛合金的不同，但機械可靠性卻與錫鉛或錫鉛銀合金相同或更勝一籌。
出色的回流工藝窗口提供了良好的 CuOSP 焊接性，能夠出色地熔融愈合多種沉積尺寸，具有出色的抗隨機錫珠形成性以及片式元件間錫珠性能。ALPHA OM-338-PT 采用的配方可產(chǎn)生出色的焊點外觀。此外，ALPHA OM-338-PT 的 IPC III 類空洞和 ROL0 IPC 分類能力確保了最大程度提高長期產(chǎn)品可靠性。
- Maximizes reflow yield for lead-free processing, allowing full alloy coalescence at circular dimensions as small as 0.225mm (0.011”) with 0.100mm (4mil) stencil thickness.
- Excellent print consistency with high process capability index across all board designs.
- Print speeds of up to 150mm/sec (6”/sec), enabling a fast print cycle time and a high throughput.
- Wide reflow profile window with good solderability on various board / component finishes.
- Excellent solder and flux cosmetics after reflow soldering
|
