Component shortages often force manufacturers to use the open broker market, a path filled with risks like counterfeit parts. At Bester PCBA, we refuse to gamble with your product. We enforce mandatory, multi-layered guardrails—including XRF analysis, decapsulation, and marking permanency tests—to ensure every component is authentic and reliable before it ever reaches your board.

Generic selective solder pallets often fail with complex assemblies, leading to scorched components and solder bridging. We treat the pallet as a piece of custom process-control hardware, sculpting it for thermal management and pairing it with a data-driven soldering program to eliminate guesswork, achieve zero defects, and ensure maximally efficient, honest cycle times.

Premature LED dimming, or lumen droop, is often misdiagnosed as an electrical issue. The root cause is thermal: heat trapped at the LED junction due to voids in the thermal stack. This article explains why focusing on thermal interface materials and manufacturing processes like vacuum reflow is critical for creating reliable, long-lasting LED products.
