PMTC SAC305 Pb-free Solder Spheres

CAPLINQ lists all its prices without taxes, shipping payment charges or discounts. CAPLINQ has entities in Canada and the Netherlands, and if your shipping address is one of these two countries, applicable taxes will be applied.

If your shipping address is to the United States, we request your company’s Employer Identification Number (EIN) or Tax Identification Number (TIN). This is a unique 9-digit number assigned by the IRS and is required for all cross-border shipments. Failure to provide this number could result in delays to your order.

If your shipping address is within the EU, but outside the Netherlands, then we are required to request your company's Value Added Tax (VAT, BTW, MwSt) number to be able to ship the goods tax-free. For all other countries, not taxes are levied to your orders.

All prices shown are ex-works CAPLINQ, but during the checkout process, you will be given several shipping options including Canada Post, TNT, UPS or the choice of using your own freight forwarder. Depending on your shipping address, the shipping charges will be calculated as follows:

• Europe, Middle East, Asia and Africa: Shipping from CAPLINQ Netherlands (Amsterdam)
• Canada, USA, Mexico and South America: Shipping from CAPLINQ Canada (Ottawa)

The products listed are the most standard products widths available. We try to keep stock on all the standard widths, and otherwise require a few days to slit the jumbo rolls. Goods usually ship within 72 hours. Custom widths, lengths and thicknesses can be made to customer specifications, though minimum order quantities often apply. Contact us for a quotation.

CAPLINQ also accepts orders by Corporate Purchase Order. Please Contact us to find out more.

This general purpose, tin-lead solder alloy is composed of Sn63Pb37 and remains the highest volume Tin-Lead solder alloy sold today for companies who have not yet made the transition to Lead-free (Pb-free) soldering.

Profound Materials was founded in 2000 to manufacture and market tin-lead solder spheres for the microelectronics industry. The company has expanded to occupy a 2,100m2 (22,600 sq.ft.) facility in Kaohsiung, Taiwan where it now manufactures the widest range of solder ball offering with the tightest diameter tolerance to its customers. Early in 2006, Profound Materials achieved its TS 16949:2002 certification and now develops and manufactures its own line of low alpha ball and electro-plating solder spheres.
