Of het nu gaat om lage volumes, hoge mix of massaproductie, het selecteren van geschikte procesroutes en kwaliteitsmethoden op basis van productkenmerken blijft van fundamenteel belang.<\/p><p><\/p>","protected":false},"excerpt":{"rendered":"<p>Het PCB-assemblageproces is een systematisch productieproces waarbij elektronische componenten op printplaten worden gemonteerd. Nauwkeurige controle van het drukken van soldeerpasta, het met hoge snelheid plaatsen van SMT-componenten, temperatuurprofielbeheer voor reflow-solderen, meerdere kwaliteitsinspectiemethoden, assemblagetechnieken met doorlopende gaten, uitgebreide functionele teststrategie\u00ebn en processen voor reiniging achteraf.
