Abstract:
Pro-ecological technologies used in manufacture of printed circuit boards
Eldos is one of the biggest Polish printed circuit boards producer. From the year 2004 Eldos is able to manufacture printed circuit boards according to the RoHS directive. From the Eldos? clients, the biggest interest in lead-free solder finished PCBs (Immersion Tin or ENIG) can be seen in automotive and industry electronics. Despite the approaching term of lead ban from electronics (the 1st of July 2006), lead free PCBs are still less than 20% of overall PCB?s production. Eldos accomplishes its pro - ecology development strategy by participation in research projects partially founded by European Commission or Polish Government:
1. PCBs with High Solderability Tin Coating for Lead-Free Soldering ? PRINT;
2. Removal of Hazardous Substances in Electronics:
Processes and Techniques for SMEs - GreenRoSE ;
3. PL Research Project: Implementation of HF laminate for pcbs for lead free soldering. (Wdrożenie bezhalogenkowego laminatu na podłoża płytek drukowanych do montażu bezołowiowego);
4. Flexible Circuits Processing, Performance and Reliability using Lead-Free Soldering Process ? FLEXNOLEAD;
An important issue in lead free technology is the cost of manufacturing. The cost of materials and water in eutectic tin-lead Hot Air Solder Levelling process is definitely the lowest. Quality of water is a major factor affecting solderability of lead-free surface finishes. Therefore, not only the bigger consumption of water shall be expected, but also the share of demineralised water in the lead-free processes will increase.
Comparing to the overall cost (material, water, electricity) of the Sn/Pb HAL surface finish, after the RoHS restrictions become effective, the increase in surface finish costs shall be expected, correspondingly: 350% for immersion tin and approximately for ENIG 1400%.
