Lead Free Solder Bar Electroloy SB-SN100CL

Lead free solder bar SB-SN100CL is a lead-free solder containing tin, copper, nickel, and other proprietary elements that make this alloy suitable for Hot Air Solder Leveling (HASL) process. 

SPECIFICATIONS LEAD-FREE SOLDER BAR SB-SN100CL

CHEMICAL COMPOSITION OF THE ALLOY

The excellent portability of the SN100CL lead-free solder bar ensures no bridging on the fine track pattern.

Good penetration of small diameter holes & uniform coating thickness and smooth luminous finish. The SN100CL does not corrode copper on the wall and shoulder quickly through holes.

– Quality of copper coating and rails is maintained

– Less maintenance is required to maintain the composition of the weld pool

– The presence of nickel slows down the diffusion of copper and slows down corrosion

CHARACTERISTICS OF LEAD-FREE SOLDER BAR SB-SN100CL 

Electroloy has entered into an agreement with FCT Asia Pte Limited to manufacture SN100CL lead-free solder bar alloy with a patent license from Nihon Superior.

All the final finishes available in the market today have merits and demerits. Many in the PCB industry are concerned about switching from HASL to a less forgiving final finish as they transit to the up-and-coming lead-free era.

The patented addition of nickel to the tin-copper eutectic offers the following advantages: 

o Low-cost lead-free alloy

o Low dross than another lead-free alloy

o Excellent fluidity with very uniform and flat surfaces

o Bridge free coating and fine pitch circuitry

o Low copper erosion

o Good shelf life

o Minimal attack on stainless steel pot

o Close to the eutectic temperature

o Easy to manage alloy composition

o Compatible with both 63/37 and lead-free final assembly 

– Brand & alloy codes are embossed on the surface of each bar.

– Each bar has a mass of about 700 – 900 grams.

– Physical size is about 330mm x sides equal to 24mm.

– Packing: SB-SN100CL lead-free solder bars are packed in “Green” carton boxes, each box is 20kg. Each box contains the following traceable information: supplier, grade, product code/type, batch number, and weight per box.

APPLICATION LEAD-FREE SOLDER BAR SB-SN100CL

– The SN100CL lead-free solder bar alloy can be used in both vertical and horizontal HASL machines. 

– As the SN100CL solder bath is used, copper tends to dissolve into the solder from the bare board. If the copper content of the solder bath exceeds 0.85%, there is likely to be an increase in the incidence of bridges and overall graininess. 

– In order to maintain the proper copper level in the bath, Electroloy recommends the SN100CLe as the top-up alloy. 

– The recommended operating window for copper is between 0.5 and 0.85%. Verification of copper content is easy with lead-free solder bar Pot Analysis offered by Electroloy. The statistical analysis of your solder pot will help you monitor the copper level over time & make critical decisions to achieve good production yield with the SN100CL bars.
