Ball / Land Grid Array Sockets EP patents 0829188, 0897655 US patents 6190181, 6249440 Patented in other countries. Screw Lock Type E-tec is now the leading BGA socket manufacturer. Sockets range from 5 x 5 upwards and some of the existing patterns are shown on the following pages. Many more exist and your exact requirements can easily be added to our extensive product library. The SMT socket is simply placed and reflowed onto the PCB in the same way as the chip and occupies only a small amount of additional board space. The 1.27mm pitch screw lock socket extends ≈ 6,00 mm beyond the outer ball row with no fixing holes. We aim to solve your requirements - many different terminals and configurations are available. Your custom sets our standards! Please note, we will always request the chip data to ensure we offer a compatible socket. SMT Style Important Note: Please check the ball diameters & heights of your chip prior to ordering the standard E-tec BGA (BPW/BCW) sockets. Any deviation has to be communicated to E-tec in order to check compatibility with the standard socket design and if necessary to obtain a special order code adapted to your chip dimensions. The standard solderball diameters & heights are the following: PCB Pad Layout Pitch ball diameters min/max 0.25mm / 0.35mm 0.25mm / 0.50mm 0.40mm / 0.55mm 0.50mm / 0.70mm ball height min/max 0.15mm / 0.30mm 0.15mm / 0.30mm 0.25mm / 0.45mm 0.30mm / 0.50mm 1.27mm & 1.50mm a) plastic chips (BPW) 0.60mm / 1.00mm b) ceramic chips (BCW) 0.60mm / 1.00mm 0.50mm / 0.70mm 0.80mm / 1.00mm 0.50mm 0.65mm 0.75mm & 0.80mm 1.00mm Ø 0,70mm/.028“ if pitch 1,27mm Ø 0,60mm/.023“ if pitch 1,00mm Ø 0,50mm/.019“ if pitch 0,80mm Ø 0,30mm/.012“ if pitch 0,50mm dimensions if BGA Socket pitch 1,27mm with contact type 30 Coplanarity 0,10mm/.004” Specifications Soldertail Style Mechanical data Contact life Retention System life Solderability Individual contact force Max. torque for retention screws Soldertail: Ø 0,45mm/.017” Ø 0,29mm/.011” Ø 0,29mm/.011” Ø 0,25mm/.010” if pitch 1,27mm if pitch 1,00mm if pitch 0,80mm if pitch 0,50mm Material Glass Epoxy FR 4 Brass BeCu Insulator Terminal Contact PCB Hole Layout 10.000 cycles min. 1.000 cycles min. exceeds MIL-STD-202 Method 208 40 grams max. up to 800 pins = 7cN per meter or 10 oz per inch as of 800 pins = 7cN to 10cN per meter or 10 oz to 14 oz per inch Electrical data Contact resistance < 100 mΩ Current rating 500 mA max.
